Sig Sauer P220 .22LR Conversion Kit Range Report.

[Crazed_SS]

I got this kit a couple weeks ago and finally got some time to really play with it. I couldnt find the P220 version in any stores. They all had the P226 and P229 versions.

I was debating buying this thing for awhile because it costs $300+ and for that price, you can buy an entire .22 pistol. I was thinking about a mosquito, but I heard to many horror stories. I went on the Sig Forum and saw that these 22 conversions have really good reviews when compared to mosquitos.

The kit comes with the .22 slide assembly and one 10-round magazine. The sights are adjustable and it comes with a little too to adjust them. As you can imagine, the kit is cake to install. Just take off your factory sig slide and put the .22 assembly on. The build quality seems pretty good. It is noticeably lighter than the stand Sig slide..

I put about 300+ rounds through it and it was VERY reliable.. Other than some stand .22 issues like a round not going off every now and then, it worked perfectly. The magazine fed reliably and the slide cycled perfectly. It is also decently accurate and I was able to tear some ragged holes with it. My P220 has Crimson Trace grips and with the cheap .22 ammo, the gun is now a very fun range toy. I can sit there all day punching holes.. The ONLY thing I dont like about the kit is the magazine does not lock the slide back on the last shot. This is by design. Otherwise, the kit is great. It allows you to practice with a full-size gun and blast .22s out of it. It would be very useful for working on your trigger discipline on a sig.

Here are some pics..

Good stuff. I think the kit is pretty good -- I've had one for the P220 and P226.

One tip: hold in the mag release while you insert the mag otherwise you'll wear the area where the mag catch holds the mag and you'll eventually need to replace the mag.

I got the stainless, coated guide rod, the upgraded mag spring and the aluminum mag follower (which holds the slide open after the last round) from sigpower.com (his upgrades are well recommended on sigforum). I'd highly recommend the guide rod and follower upgrades.

Just about 7 yards.. just capping off rounds 1 per second.

I tried taking some well-aimed shots and it was grouping real good.. I left that target hanging at the range

thanks for the report!

I swear I saw it at Project 2000 in El Cajon.. give them a call.

Sweet,, thanks for the tips!

The Sig conversion kits are well worth the money. The thing I like most about them is I get to shoot on the platform I use the most and it doesn't cost me an arm and a leg. It doesn't take long to make up for the cost of the kit because the .22lr is so much less expensive than the 9mm, 40 or 45.

A shameless plug....I sell the kits for $315 delivered to your door ($375 retail) and have extra mags in stock too.

My P220 conversion kit didn't work at all in the first and only range outing. Mis-fed every round. That was about 6months ago. Haven't had a chance to go back to resolve the issue since.

It's the plastic magazine; I had the same issue. For the money it's a disappointment. Sig even replaced (or smithed) the mag catch during the second trip under warranty.

I am going to buy a Browning Buck Mark or a Ruger Mark II/III for my rimfire plinking. There's nothing fun about executing a couple of 'tap rack bang' procedures every freaking mag.

I can't take credit for the mag tip -- I got it from Jeff (sigpower.com): https://www.collectors-society-slabs...d-Information/

BTW, I'd use care when ejecting the mag as well (not just insertion), maybe press up on the mag, push in the mag release, then let the mag drop -- anything you can do to minimize wear on the mag notch is probably good. I started to have problems after about 1000 rounds.

Jeff at sigpower.com is a good guy who stands behinds his products. I really love the metal guide rod and all of his upgrades. The only thing we can't use in CA is the mag plug -- I've ordered all other upgrades and am happy with them all. I'm partial to the cera-hide coated guide rod but I'm sure the uncoated one is just fine.

In terms of ammo, the CCI mini-mag is the most fun (but more costly). I haven't really had any problems with any bulk brick (CCI, Federal, Winchester, etc). But I suggest you test out a small batch of new ammo before buying a lot -- some people have found their kits to be somewhat ammo sensitive.

I have found that I need to clean after about 250-300 rounds; after that, I start getting feed issues. But it just takes a quick pass with a bore snake and a quick wipe down of the feed ramp area -- shooting in less than 5 minutes.

Have fun w/ the kit.

I am interesting in Sig 220 conversion but concern about Sig 220 frames are aluminum, will they wear out quickly with 22LR shooting? One session can easily shoot 300 rds, twice a month, so a year I shoot 7000 rds of 22LR, is it too much for an alloy frame?

[konata88]

I haven't heard of any issues. The 45 slide is made from stainless which is harder than Al and is fine. Do you have reason to believe that the aluminum slide for the 22lr kits would be more harmful than the stainless slide used for 45?

I wouldn't have thought it, but indeed the rails on my P220 are mightily scratched up after a few hundred rounds through the conversion kit; the stainless steel slide never put that kind of wear on the finish and I've put many more rounds of full-power .45ACP through that frame than I have .22LR.

I haven't looked closely but it suggests there are some burrs or other machining imperfections on the aluminum slide of the conversion kit I have.

Interesting. Sorry to hear that. It might be kit specific. I've put through 1200+ rounds w/out issue. I lube with both an oil (militec) and a grease (twb25) -- probably wouldn't help with a burr in the slide but other than that, I run it fairly wet.
