Bruce,

I'm still waiting for some items that were suppose to be shipped out on Fri, 18 Jan 2013 and then on Mon, 17 Jun 2013 and have not had any response from your email so i thought I might catch you here.

Base Pads - I don't have any on my mags, makes use difficult with the magwell.

New Mag Springs - You said this might help the feeding.

10rd Mags - Awaiting delivery on these.

Every round fired gets a significant dent in the side of the brass, I have been able to diagnose the problem - when ejected every case hits the slide (upper rear corner of the slide ejection port), I assume this is something that could be eliminated by adjusting the extractor. Thoughts?

Thanks!




Marcus, I'm sorry I responded to your questions so late! I'll call you tomorrow to discuss what we can do to adjust the 10mm and get mags to you. We have some new stuff that will help that I'm not quite ready to disclose here. Thank you! -Bruce


I shot you a line a few days ago and will try you again Monday. -B


Bruce, I will be available from Friday evening EST throughout the entire weekend by cell and always through Email. I would love to hear where we are with these parts and thoughts of the functionality. Thanks, Marcus.


Bruce, Still looking for help on the above items... Looks like the last poster has some fancy base pads on his mags.

Going kinda off topic, but has anyone compared a P220 10mm with a Grayguns 10mm yet?

And what about parts interchangability? Sig 10mm mags and recoil springs in Grayguns 10mm?

Bruce, Tim is suggesting mags and their 10mm locking insert might be worth a try to improve reliability. I still don't have the mags with basepads to allow proper reloads with the funnel you added.

Does Bruce still do this conversion on the 220ST now that Sig has come out with the 10mm version? I own a 220ST, but can't really get the standard 10mm 220 because, well, I live in Kalifornia! Frown Was thinking about doing the conversion. Anyone know and can ballpark an estimate for conversion? Thanks.

I wound up being able to pick up one of the original converted 10mm P220s on the aftermarket. The gun is amazing.

What kind of commercial ammo have you folks found that works well? I found that HPR 180G FMJs get stuck on the feed ramp. I haven't yet gotten ahold of any other "full power" loads other then the HPR ammo.

American Eagle and CorBon range ammo feeds fine in mine though. I also found Barnes "Vor-Tx" hollowpoints feed well.

It came with a very limited selection of magazines for my liking.

I have been attempting to get in contact with Bruce, but so far our schedules have not met.

Does anyone know if Sig's new 10mm p220 mags will work in the GrayGuns conversion p220s?

Additionally, does anyone know what recoil and main spring weights are used in these guns? I'm looking for a source for a few spare springs.

In case Mr. Gray reads this... I have one question specifically for him: My pistol is currently equipped with adjustable target sights in the standard dovetails. These sights stick up quite a bit. Is it possible to fit an X-five style rear sight to the slide that is lower to the slide?

Mine will feed any ammo I've put through it. During the first 100 reds I had a few FTF with Hornaday. But no issues since then. I've run Atomic, Hornaday, Amscor, American eEagle so far. Plus a variety of hand load recipes finding the one I like best

The new Sig mags do not work. I just received one from Sig the other week and tested it. Does not feed correctly It maybe an easy fix, waiting to hear back from Bruce

this months American Rifleman magazine has an article on this gun , by Wiley Clap.

a third of the article is 10mm history , and the balance of the read is very vague ,
almost like he read other articles about it and then went and shot it for awhile.

If you do not get the magazine, the article
does not have much to offer.

Any word on when we can expect P220 Nitrons in 10mm?

Can't wait to get one of the first to roll out of the factory.

Hey, um, I hate to be the bearer of bad news, but the Nitrons came out around July of 2015. You can shop around and hope for one every now and then, but there are two of them on that popular gun auction website right now...

Sorry, I meant "standard" "base model" P220s in 10mm.

Only thing on there are the Elites and SAO models.

I want one so bad. But I SO cannot afford one. Guess I'll have to wait until somebody sells a used one.


People say I'm paranoid because I have so many guns. If I have many guns, what do I have to be paranoid about?

After all this time, my GGI P220 10mm is still my favorite Sig.
Thanks, Bruce and company.
