My pistols are P228 and P239 9mm. I have added a P245 and have a couple questions about it:

1. What ammunition do y'all favor for this for carry? For range use, I have been using the 100-round Federal Value Pack, 230 grain. If I foresee a lot of range use, I will probably start reloading.
   
   
2. Compared to the P228 and P239, the trigger pull is really, really, heavy. Heavy to the point where I think it's affecting my accuracy. Groups are spread out much more than with my 9mm SIGs, no matter how much I slow down. Any suggestions here? I was thinking of Gray Guns but the wait time is so loooooong. Maybe Robert Burke? Or back to SIG? Or is there something a person of limited skill, like me, can do?

Install a lighter mainspring.

I have to admit, I have limited knowledge as well as limited skill.

Question: Mainspring and Hammer Spring the same thing?

Top Gun shows Mainspring, but no choice of weight (unless I missed it on the website).

Wolff website shows no Mainspring, but it does have Hammer Springs, however no mention of SIG P245. Will the P220 work? If so, they state that the standard spring is 22 lbs. They show a kit, their SKU 26574, with one each of 18, 19, and 20 "reduced power" for the Browning BDA and P220 with serial numbers below 219166. The serial number on my P245 is not in this series, it is C01293.

Main spring is hammer spring.

V-Tail,
First remove the right grip panel to determine if you have the plastic mainspring base or the older metal base.

If you are handy, Grayguns has drop in kits for P series guns.

Sent my P245 to Robert Burke. Was home in under 2weeks. Wonderful trigger. Can't go wrong with Robert.

I'm surprised to see this comment. I find the stock trigger on the P245 to be one of the best I've experienced. What's the condition of this gun?

I've a P245 and the trigger pull is non-distinguishable from any other of my P-series guns. DA or SA. I'm not saying that each is exactly the same as I have several covering the gamut of years of production. I'm just saying that my P245 is as good as the rest.

But, just like anything that's mass produced there are probably some that left the factory better or worse than the majority. You may just have a rough one. I'd say to first do a total field strip and scrubbing and put things back together and apply some quality oil. Then shoot the bejeezous out of it and see if things get better on their own.

My local expert (occasional Gunsite instructor) suggested that holding your pinky finger out away from the grip helps with the accuracy of those small-gripped pistols. It certainly seemed to help me.

And helps when sipping coffee and tea.

Grip is essentially same size as my P228. Grip is larger than my P239. My P228 and P239 produce much more consistent groups than the P245.
