So I cant explain why, but I've wanted to get my hands on a Sig Sauer Mosquito since they first came out years ago. Well, last night I bought one from another member on here. I've read alot about how Sig recommends CCI ammo for it, and every forum I've looked at, people report these pistols are very finicky about what ammo functions in them. Well, today I took my new (to me) gun to Bayou Dragon, fed it about 300rnds of mixed brand/grain/velocity ammo, and I didn't have a single malfunction of any sort. I also brought my 80% AR with me to shoot, and ended up barely touching it because I enjoy this lil pistol so much. I also talked to a couple guys that didn't know about this forum. Hopefully they'll sign up soon. All in all though, The Sig Sauer Mosquito is surely a winner with me. I just need to tighten up my groups at 25-30yds with it.
