.22LR Conversion Units
I have an unfired one that sits as I bought a classic model 229 for the lower to run an old 228 parts kit upper from when twogunjay still sold them.

Might I ask whose grips those are Grumpy and are they aluminum or g10?


A Perpetual Disappointment...

I had a P250 .22 for a while...22LR upper on a standard P250 lower. It wasn't sold as a conversion unit, but that's essentially what is was. I bought it because it was as close to having a training version of a P320 in .22LR as I could get.

It was ok if you like to practice clearing malfunctions, but was never really truly reliable, at least not compared to a purpose-built .22 pistol. It was unreliable enough to be annoying, and I learned that I could get more value out of trigger-press practice by dry-firing my actual P320 than I could with that thing.

The .22 trainer idea ended up being kind of a bust. That left it as basically a range toy so I ended up getting rid of it as my Ruger MkII and MkIV are far better handguns in .22LR. I don't miss it.

Those are aluminum grips I bought from SIG when they had them on sale during closeout sale probably about 10 years or so ago.

I have conversion kits for 220, 226, and 229. They all work, but are not the most reliable. I have a couple mags for the 220 and 229 from GS Designs (not sure I got the name correct), a Canadian firm that makes 3D printed mags that have a hold-open tab. It works, but not consistently. Some guys have had better luck with them. For me, factory mags seem to work the best. As mentioned, Taylor makes followers and new spring pegs that allow more ammo to be loaded in the mags. However, the feeding from those mags can be iffy. I went back to the regular spring plugs. The followers are nice though, because they keep you from firing on an empty chamber.

Just curious what you were running in it. I have one of those. I haven't shot it a lot, but so far it's been 100% with Mini-Mags.

I also have one that's been 100% through several hundred rounds of Mini-Mags. Don't remember if I've tried anything else (or what I had for breakfast).

I shot a variety of ammo through it, probably several thousand rounds over the time that I owned it. Most of that would have been Federal Automatch, but there was a lot of other stuff mixed in there too as I went through the troubleshooting process. I don't recall specifically shooting minimags, but there were probably some. I had failures with a bunch of different types of ammo, mostly light strikes. I was able to work through a few feed issues with the magazines and a small chambering problem, but I could never fix the light strikes to my satisfaction. FWIW I also had some light strike issues with my center-fire 9mm P250 as well (two separate guns and FCUs), which is part of the reason it went away. I just don't think they're sprung heavy enough to consistently ignite rimfire primers. On the upside, being DA you can often just pull the trigger again to get it to go off... shouldn't have to do that, though.

I'm of the opinion that if a .22 semi-automatic requires specific, overly expensive ammo to be reliable, then it's not a reliable gun. Unless it's fulfilling a very specific role like high-end target shooting or something like that, I'm not willing to tolerate that kind of pickiness. There are guns out there that will run everything you feed them...my MkII being one example (although my Mk IV has been a bit of a headache, but I have too much wrapped up in that one to just dump it), as well as the Browning Buckmark, and I hear good things about the Taurus TX22.

Blast from the past.
Doing the "SIG .22 math" 13 years ago:
I wanted to end up with a P229r in both .40 S&W and .22 lr.
(I will just use MSRP for the example)

P229r vs P229r Classic .22 + caliber change kits for both:

Example #1:
P229r .40 S&W = MSRP: $1068
.22 lr Kit for P229r .40 S&W = MSRP: $285
TOTAL: $1353

Example #2:
P229r Classic .22 = MSRP: $608
.40 S&W X-Change Kit = MSRP: $356
TOTAL: $964

DIFFERENCE: $389
I am NOT complaining, but I AM wondering.

So I bought example #2, BUT my local dealer was selling the Classic .22 for $449.99 which included the SIG coupon for the .40 S&W X-Change Kit @ $299.99 shipped!

That’s an additional $214 savings, so my price was: $750 for the 2-caliber set.

I remember seeing those. I, too, noted that buying the .22 and a caliber exchange kit was cheaper than the other way around. Just didn’t have the cash back then nor the interest. I was a 1911 guy.
