Has anyone tried CCI Standard Vel. rounds in their Mosquito? I have shot them using the white (light) spring after the break-in and found them to be very accurate shooting paper. The CCI Pistol Match worked the best but the Standard Vel. shot as good as the Green Tag did for me. For just blasting away cheaper ammo works well enough. It is nice to change the ammo and have it still function right.

Wranger, been here for 10+ years and love it. Born in Henderson (your wife would know it) grew up in Houston and hated it. Love east Texas.

400 shots and 7 failures first time out of the box, I'm very happy with this pistol.

Dave you are correct, the gravel is on the double action pull and the reset getting to the single. The single pull has a little creep but just a little with no overtravel that I can tell. I am thinking that some of the gravel is caused by the plastic trigger rubbing on the frame sides.

I had never heard of KG Coatings before and did some research on the internet about them. Sounded like some good stuff. I have an assortment that I ordered that will here tomorrow and I'll give it a try.

I'm going to split it down and go through pages 5-7 (I printed them out) today and shoot it again tomorrow.

Has polishing the feed ramp done any good? It works wonders on a 1911 and I've done it to both my P239's with very good results.

I have read about some people having ammo feed better after polishing the ramp. I have not needed to try it. I found just putting the KG molly powder on a Q-tip and rubbing it into the ramp worked well enough for me. If you are doing the trigger job and have the moly powder you might rub some on the sides where the trigger bar will contact the frame shell and the plastic frame as well. I generally just rubbed it on with a Q-tip on any area where there could be two surfaces coming in contact as I was putting things back together. I don't think dry lube will hurt anything in the trigger area. I did go back in later and added a little oil to the moly for the sear. I was thinking the oil may make the moly stay there a little better. There shouldn't be any burned powder in that area to contaminate it and create other problems. Please let us know what you think of any improvements you find in your trigger. Also if there are any changes we need to make as well.

Well, this was a fun read. I'm going to try to find some time in a couple of weeks to see about taking mine apart and looking at what needs to be polished...

I was curious if polishing the ramp would help or not. I think I might buff on it a bit and see what happens.

Is anyone applying any lubricant at all to their rounds? I tried spaying a light coating of silicone on last night and my failures went down to 1 in 500. Not sure if it is just loosening up or if the silicone helped.

I pulled my mags apart before because they just don't feel good while loading or pushing the spring up and down. I think I'm going to pull them apart again and take a much closer look. For some reason I really think the mags are causing the majority of my problems.

Now that my wife is getting comfortable with her 380 I might get to shoot this thing a little more. It is a nice change of pace compared the the 9 and 40.

There was one person that applied One Shot to his rounds. One Shot is a case lubricant used when you are re-sizing brass for reloading. If I were to ever use a lube other then what the rounds have on them from the factory I think this might be the best. If you do a search on this site and put in One Shot Lube and maybe add Mosquito you should find the post.

I like the idea of the one shot and I never met a well polished ramp I didn't like. MIne now shines like a piece of jewlery. Good luck guys they are fun toys to own and shoot.

Well it seems it is time to take the old Mosquito apart to correct a minor problem. I have been having a problem with the slide not locking to the rear after the last shot is fired. It happens every 4 to 5 magazines. I didn't use the same magazine again in this gun after it did happen so I pretty much figure it is in the gun. I probably have too much build up around the spring for the slide catch. I have only fired a little over 10,000 rounds and it still has never been taken fully apart. I might even have to get a dremel tool to polish the ramp and so it shines nice too.

I bought some dremel polishing bits and pieces this weekend. I hope to have time next weekend to shine the ramp up a bit. I still think it and possibly the magazines are my main source of problems.

It is getting better with use, just not what I expect from a Sig as far as reliability goes...

Dave wich spring are you using now? I had the same thing happen yesterday and have not yet looked for the source. I was using the weak spring.

I was using the weak spring too. Since I was shooting Mini-mags and Standard Vel. rounds the white spring works better. My thought is that the there may be something to adjust or just clean to fix the problem. There may be some junk in the spring for the slide catch lever making it come up a little slow. It doesn't happen all the time. I have 4 magazines for each Mosquito so I can change them around if needed. They all work fine on the newer one so that is why I think it is something internal.

Hi all, I'm new here. Great thread Dave! I just read the whole thing.

A few weeks ago I bought my first gun, a SIG 239 SAS 9mm, and I'm very happy with it. I've been thinking about buying the Mosquito next, and thanks to this thread, I'm going to order one

I have a question about auto-loaders for the clip. I have a nice one for my 9, but it's too big for a 22. The Ruger Mark III has a really awesome clip loader, but it definitely doesn't look like it will work with Mosquito clips:

http://www.brownells.com/aspx/ns/store/ProductDetail.as...ULTIMATE+CLIP+LOADER

Question: do you load bullets into your mosquito clips manually? I have no desire to do that if it can be helped. What loaders have you found that work with mosquito clips?

Thanks!

Hey Dave,

Where did you get your tactical light for your mosquito? I am looking into getting one.

Thanks!

I just push down on the pin that holds the follower. There isn't all that much pressure compared to many magazines. The only one I have found easier to load without anything extra is the P22. I now have a total of 8 magazines so if only shooting one pistol I don't have to reload until I have shot 80 rounds. In the future I want 2 more so I can have 50 loaded for each gun. Really just having a couple of extras is always nice. The Mosquito magazine does cost a fair amount.

Now I do use a loader to help me with the 9 m/m magazines. I don't see any need for the Mosquito.

By the way welcome to the Forum Pow be te Pow.

I sorry to say I don't have a tactical light. I do have a couple of scopes, laser and even a red dot for the Mosquito. Maybe some of the others here can answer that question for you.

Also welcome to the Forum.

wcruze1... you might want to check into the Streamlight (also has a laser option) and search E-bay for different options.

Just a quick update on the status of my skeeter. After just having the gun for 9 days, including shipping I received my Mosquito back from Sig and it did indeed have a broken trigger return spring.

The guy at Sig's customer service said they fired 50 rounds of CCI mini mag after replacing the spring with no issues. Hopefully I will get a chance to put some rounds down range tomorrow but more likely it will have to wait until the weekend.

On a side note is there a way to remove the plastic frame to spray cleaner on the internals of the Mosquito? The guys at Sig said my skeeter was VERY dirty internally.

Just take it apart by following Dave's pictures and comments. It's not hard to take apart and re-assemble if you pay attention!

On another note... since I couldn't find any parts online (or anywhere for that matter), the gun was sent into Sig for repair. It's nice to know that you had a quick turnaround.

It is good to hear you got it back so soon.
Excam_Man is right. Just go to pages 5 through 7 and the information is there to strip everything except the firing pin assembly. I like using Moly since nothing seems to stick to it so things stay cleaner then using something oil based. After all the metal parts are good and clean just lubricate and put it back together. Nobody says you need to do trigger work while you are in there. After so many rounds through yours it should be real smooth now.

I finally had time to take a look at the Mosquito that has been occasionally having a problem with the slide not locking to the rear after the last round is fired.

What I found is the ear that locks the slide was not worn nor rounded. I thought that may be the case. Instead since the notch on the slide is only on the outer side. The latching bar was just catching about half of it. That is half of the ear on the bar was catching the notch on the slide. I made a very small tweak and now it normally rides about 1/2 mm away from the frame of the pistol. It does float a bit naturally side to side. The main objective was to have the slide locking bar ride .5 mm further to the outside of the slide so it would grab the notch better. It is a bit late so I hope I made this understandable. I put moly powder on both sides of the locking bar and rubbed it in with a Q-tip. It seems to be a little more positive now. I will have to see how it works after shooting a few hundred round to be sure that fixed the problem.

I made a trip to the range today. It seems making the minor tweak in the slide catch lever made a difference. The slide locked back every time this trip. I used all the magazines and they all worked just fine. Everything else worked great on the Mosquitoes so it was a good trip.
