Slide falls without hitting stop

[Peplow530]

My SP-01 is prone to going into battery when slamming a new mag in after running dry. Is this pretty common with a lot of CZ's? I always thought it was pretty handy when competing, but the other night it happened before the mag was fully seated and it didn't strip the top round. Kind of a bummer since I lost 1st place by less than 3 seconds.

Is there a way to insure this doesn't happen? I never can tell weather I will have to hit the slide release or not.

Several threads discuss this with many brands of pistols.
I like the slide to release,  but never read of one releasing 'before' the mag hit the battery rail--fully in. 
I'd try to make that happen again at home and see if you were pushing the mag release or what the heck caused the slide to let go.
A couple of years back,  I accidently released a mag at a match with my weak hand.
