I bought my daughter a "Raspberry" Sig-Sauer Mosquito for her 8th birthday. It was the one she picked out...I was steering her toward a Browning BuckMark, or a Ruger MkIII. Anyway....the day came, we took it out to the range on the back 40 acres of my home, and with 6 different types of .22lr ammo....the pistol would NOT fire through one magazine without multiple failures. FTF, FTE, FT-Fire....the whole gamut of stoppages and failures. This was with EVERY type of ammo. I cleaned it repeatedly. I made sure it was properly (not overly) lubricated. I was not terribly concerned at first, figuring that it would take a hundred or so rounds to break in....but after well over 250 rounds....it only got worse. I contacted Sig...and got a big bunch of BS about "Sig quality....horse **** horse **** horse ****...." So....I took it back to the shop where I purchased it (new), and the owner who loves me as I have bought literally tens of dozens of firearms from them over the years. She took it back, and swapped me out for a minty 6" Smith & Wesson 622.....which functions PERFECTLY. So, in speaking with people whop have purchased the Mosquito all say the same thing...IT SUCKS.
