I’m thinking of doing it, to reduce weight, will it be just as reliable with my G17L barrel (cut, and threaded for suppressors) as my standard slide is under extreme conditions?
I’ve done similar. I milled out the top of a G17 slide to mimic the opening in a G34/35 slide. I run it primarily with a suppressor, and it does just fine.
you’ve got more space to let crap in… so that would hurt your reliability somewhat… but i don’t see why it would be otherwise less reliable. slide mass should be approximately equal to a regular G17 right?
