I taught both my Wife and Daughter to use their support hand to release the mag with the pistols I have to be able to maintain muzzle control and target acquisition. The more I demostrate the more I am finding that I like it too (not rolling or canting the pistol to be able release the mag). It can be done with a fluid motion and quite fast. Relax support hand, press mag release with support hand, retrieve new mag, insert new mag, release slide and regrip. At no time has the muzzle swayed or drifted from the target. I started using this technique when shooting a Beretta 92s because of the heel release, just figured it would work for family members with smaller hands shooting larger frame pistols.
For me anyone press checking his pistol has an inherent mistrust of said firearm. It’s funny that for many years of military shooting (and if you think about it how many people have been taught, carried, shot) the press check is the one think that hasn’t been taught, I have never seen mags fall out of pistols when shooting, I have seen the guts fall out and it was funny but the mag was seated (pretty all stemmed for crappy reassemble or worn out floor plate on mags older than the shooter).
That being said my opinion is about carrying and using a mass produced military firearm and not a expensive one of custom made pistol
