Sig Mosquito/ GSG Firefly

[b-stick]

Anyone own one?

Shoot it suppressed? If so, how about subs? Did it cycle them?

I got one a two weeks ago. Finally got the optics mount and thread adapter for it. Tried to shoot subs, but it wouldn’t cycle. Swapped guide rod springs with no difference. Innerweb says some people are able to get them to cycle but curious to see what experience y’all have had.

Standard ammo runs fine.

Mosquitoes are notorious for poor cycling. It’s a fairly easy fix if you’re fine with gunsmith-ing your brand new pistol.

It’s still pretty quiet with supers but I do want subs to cycle. What’s gotta be done?

Try cci standards. Usually will still be subsonic in a pistol but have enough pressure to cycle.
