I bought a Misquito when they first came out, very ammo sensitive and I could not get mine to shoot with the sights. I sold it and got a conversion kit for my P226. Now this is what I was looking for, fine sights and good reliabiltiy. I sold the conversion kit when Sig offered complete guns in 22LR. Got a deticated P226 in 22 and it filled my Sig needs. Since I have centerfire M&P's, I finally got in a 22 M&P the first week of December. It too is the the grail I sought. It's more accurate than I can shoot it and just plain fun to shoot. It as well as the Sig both fit in the same holsters as ther big brothers and are fine training guns. You will not be disappointed with the M&P22. Bob!
