Ok, I have my first Blowback action pistol on the way - it has a slide lock switch on the side. My assumption is that I can lock the slide in the back position and not have the blowback feature engaged; thereby saving on CO2?

Sorry if this might be a 'silly question', but newbie to this feature.

Thanks

Doubt it. One lever is to mimic the take down lever, and the other is the slide lock. To lock back the slide to clear jams. It doesn't lock the slide from blowing back.

Right side is the safety. Sorry no way of disabling.

Hmmm, I was under the impression that if the slide lock is in place (slider is in back position locked), the gun should still be able to fire without the slider going back and forth in the blowback action.

Why not just try it & see what happens, it will work or not - just do it - :roll:

It depends on the model but for the vast majority if you locked the slide in place, more or less the same amount of CO2 is going to exit the magazine and you risk damaging the mechanism.

If you want better CO2 economy, go for a non-blowback pistol.

Would try, but gun is on order...just curious at the moment. It's a Beretta APX

I think PZAM is right ~

The design of the gun decided how much co2 uses in every shot... And in a blow back action pistol, certain amount is for pushing back the slide and I doubt we can save that...

And I think the lock mechanism you talk about is for the hold open function?!

This one?

If so, don't try it. Much like a sexually frustrated Arctic explorer, you're liable to end up blowing a seal, or worse!

Only slider is the safety on the right side. The slick lock on the left is only to lock the slide back or release it when pressed down.

Even If you held the slide from blowing back. The valve would still waste Co2. Because the slide catch, lock or whatever name people call. Has nothing to do with shutting off gas. So there still be gas supplied to the blockback mechanism.

My 20 plus years with firearms. No slide lock will lock the slide from moving. Only a few safeties will. But then again it will not allow the gun to fire.

Yup..that's the one.

Ok, I won't bother with locking the back of the slide manually. I hope that the gun isn't that fragile...I mean, if all BBs are out, the slide will lock back but during shooting, one can lose track that they're out of BBs and continue to fire away.

That is correct - the lock mechanism to hold open the slider in the back position.

That's another function of the slide stop. The follower on the magazine will push the slide stop up to engage when empty. Letting you know to reload.

APX, SA177 and 9XP are the same gun locking the slide forward will not result in less CO2 consumption but may be just may be in an increase of velocity if the barrel is long enough. On that particular gun the slide does nothing, mecanichaly as for reloading or firing BB's. You could just block the back of the CO2/blowback chamber so no CO2 could get in the chamber. That's the way I see the inner function of this gun, I may be totaly wrong, but that's the way I see that gun…

p:s this will work only for this particular gun, as far as I know it will not work on any other gun...
