Mine was sent back to sig to have the breech end of the bbl slightly widened which decreased the FTF and FTE issues but with the scarcity of CCI mini mags I finally sold mine and replaced it with a colt .22 government model 1911 which is much more ammo tolerant. Is the mosquito the ideal gun, no. But it did serve a useful purpose and was fun to shoot when it had no failures. I had about 7'000 rounds through it before I sold it.
"but with the scarcity of CCI mini mags"
.22 LR has been plentiful for anyone for the past year who has been diligent tracking websites...
...but with one caveat:
Good luck finding quality high velocity plated ROUND NOSE.
I've purchased 30,000+ round in the past 6 months - much getting passed on to others doing classes and Boy Scout stuff. The vast majority has been high velocity hollow point and standard velocity round nose. There's plenty of that to go around - as evidenced by the recent Federal 745 2100 round cans at Cabelas.
But in that same time frame:
1000 rounds of CCI Mini-Mag Copper Plated Round Nose
1575 rounds of Fiocchi FHV22CRN
2000 rounds of Winchester M*22 (Really Cheap Ammo!!!)
Those CCI / Fiocchi were split with two other persons.
Result? I like everyone else am on a starvation diet for high velocity plated round nose.
It's the one round that guarantees 100% compatibility with high velocity spec semi-auto firearms - rifle or pistol. Which means, it's the round every knowledgeable .22 LR owner really wants.
It sucks...I'm down to just 525 Fiocchi - I'm already having to switch my Mosquito's springs in order to shoot standard velocity Eley, Aguila and Wolf.
