Sig .22 conversion kit or the Mosquito ?

[bryan28]

I like Sigs so I am thinking of eventually going a P22x series. But I also want a .22 for plinking.

But if I had to decide between a .22 conversion kit for a full size Sig or get a Mosquito, which would be better?

I've heard bad things about the Mosquito, but I decided I can live with recurring jams because I'm just target practicing and not depending my life on it.

The .22 conversion kit is appealing because I can practice on the full size frame and trigger of the defense gun. But it's almost as expensive as the Mosquito (about 250-300!). And unless the benefits are apparent, I'd rather have two complete guns than one gun with two barrels/slides

Anyone have experiences that can help me out?

I can't speak to the conversion unit because I don't have one, but I can speak to the Mosquito.

I bought a Mosquito in December of 2007. I fired a lot of CCI MiniMags through it and never really had a problem. After a couple of months I got snobby though and only wanted to fire a real gun (9mm) and sold the Mosquito to a friend who wanted it.

So Obama got elected, the ammo shelves went bare, and prices went through the roof. It's just too much trouble finding 9mm and the prices are too high still but I like to shoot so it seemed to me that I needed a 22lr. Damn, why did sell that Mosquito?

So now what? Ruger? Buckmark? Neo? S&W? No, I want something that resembles a real gun. P22 maybe? Who am I kidding, I'm a Sig guy.

Yes I did buy another Mosquito - 2 tone - $315.

I picked it up Monday, brough it home, took off the slide, and took off the grips (those are really little screws so I would suggest to all to make sure and use hollow ground screwdrivers and easy on the torque). Sprayed the slide and frame with M-Pro7, ran a tornado brush down the barrel a few times, then a copper brush a few times, and then swabbed it out. Scrubbed the slide inside and out, and the frame inside and out with a tooth brush saturated again with M-Pro7. Used Syn Safe Gunscrubber to rinse everything off. Swabbed the barrel with, and lubed everything else with, CLP. Reassembled the gun with the light spring.

I went to the range on Tuesday with the Mosquito and a few boxes of Minimags. I sent 200 rounds downrange. The Mosquito went bang every time except once at around shell number 93. It just went click. Visible examination (press check) showed a round in the chamber. I cocked the hammer and pulled the trigger. The round fired. No other issues. No jams, no stovepipes, no fail to eject.

This was a function check trip to the range so I wasn't going for accuracy. I was firing somewhat quickly at paper at 25 or so feet. Even so the rounds all stayed within 4 inches or so.

Keep it clean, keep it lubed, and use Minimags (or at least recognize that there are some brands it won't like) and you have yourself a really nice plinking pistol that is fun to shoot, accurate enough, and feels, looks, and operates like a SIG.

It's just a machine, and like all machines, there are guidelines which must be followed to ensure proper operation.

And unless the benefits are apparent

it depend on how much you want to get familiar with your 226. by going with the conversion kit...even through there is a difference in weight...you're practicing with the same trigger pull and control locations.

the 22lr top end really lets you practice your DA trigger pull to get it smooth and is also good to introduce folks to shooting a full sized gun and avoiding a noise induced flinch

i did look at getting a Mosquito, but ended up getting a conversion kit for my 226ST

[trapshot68]

I have a high standard 22 (separate pistol) and a conversion upper for my 226.

I shoot my conversion more. Now granted, some people have problems with their conversions (I've read), but mine has been great. 2 fail-to-fires attributed to the round. Sometimes doesn't locked up all the way, but fixed by tapping the back. I also notice that the conversion likes to be run wet. Like on the rails and chamber hood.

Couple of reasons the conversion is fun/good
- no 10 day wait
- I already have a holster and don't have to buy new accessories
- cheap to shoot/fun to shoot
- practice same trigger pull, let off, reset, DA, etc.

Reason I don't like the conversion:
- mags expensive
- no lock back after last round. There is a follow "upgrade" but all it does is block the slide from going forward, and not actually trip the slide catch. The part almost costs as much as the mag does too......

Still, very happy with it. If I haven't shot in a while, I'll just start off with the 22, or if I feel like shooting a lot, I'll shoot the 22. Or if my friend brings his kids, I'll put on the 22.

The Mosquitos are nice. I bought one for my son to shoot. But there are better .22s (Ruger Mk.III, Browning Buckmark).

If you want something that maintains the Sig "feel," then go with a conversion kit. Since the Mosquito is a reduced-size gun, a conversion kit allows you to maintain the full-size feel while getting to use your regular 226 trigger.

buy a diffrent 22LR...its the same concept. I had a Mosquito, bought it in 08? jammed every round..the longest streak it had was three rounds with no issues....yes, I cleaned it, cycled it by hand and did all the things nessassary but it didnt want to work with me. Put 700 rounds through it...didnt want to work..sold it, got a MKIII 22/45...Very happy. From 1st to 5k+ shot, no gun issues...ftf due to ammo....and its not even clean even after 5k shots.

I have a mosquito and like the gun. Nothin bad to say about it at all. But I would go for the conversion if you want more range time with your primary weapon. If you just wanna plink go for the Mosquito.

Get a Sig Mosquito. It loves CCI Minimags.

[JPanimal]

I shoot a p228r and have the conversion slide. Since i'm trying to continually improve my shooting and I dont want to break the bank, I shoot the conversion slide 95% of the time im at the range. It is also my only handgun so as soon as I get home I swap the slide back to the 9mm one. Having two guns is fun but I like the conversion to really get to know the one handgun I have. The drawbacks (for the p228 slide) is a longer slide than the p228 so it doesnt fully fit into my holster ( I dont know if this is an issue for the 226), the sights are slightly different than my sig night sights, and a few failure to feed. The mags are expensive and I bought mine off a dealer on calguns- I couldn't find a better price anywhere else, PM me if you want to know who, Im sure he has more.
Bottom Line (IMO): conversion- the trigger time has improved my shooting leaps and bounds while keeping the grip and function 100% identical

I got the conversion for my sig p220 and I like it I've only put 100rnds through it only had one failure to feed I think it was my fault cause I loaded the mag wrong the only thing is it takes forever to load the mag I need to get extra mags but so far I'm happy with that set up I fed it cci mini mag

Get a Sig Mosquito. It loves CCI Minimags.

I use CCI and then tried other high velocity .22lr rounds that would fte almost every round. After polishing the ramp, the fte are not as frequent and non-existent with Minimags.
