Any Sig mechanics on OSA?

[CorpsVet]

I have a Sig Mosquito that won't hold the slide open. With an empty mag it stays open, but as soon as the mag moves down for removal it moves back into battery.

The slide hold back lever won't hold the slide back unless it is held in place by my thumb.

Not a big issue, but I would like it fixed.

Thanks

I had the same problem with mine. My conclusion is that the Mosquito is a POS. I sold mine.

Didn't have this problem, but I still have misfires with every box of Minimags I put through it. I'd sell mine if I didn't promise my brother he could keep it until he gets his own. Eek.

if you manually rack the chamber open on an empty mag, and then remove the mag, will it stay open?

Call SIG. The Mosquito design and manufacturing isn't at all comparable to their other pistols, but they've been very good correcting problems with them - often replacing the gun.

Sounds like the end of the catch where it hooks on to the slide is rounded or bent. If you were to look it may only take a slight tweak to the end to make it catch better or a small file to put a hard edge back on it if you want to try DIY.

Was told once that its better to pull the slide back with a full mag in or no mag at all to drop the slide down rather than to touch the release lever. Was told that the lever edge can wear or bend causing it to no longer catch properly if at all.

olyeller, yes slide closes as soon as the mags release is pushed
