Effect of Mag Extensions on Reliability?

[HoosierQ]

So many of today's hi-cap sub compact pistols have mag extensions with pinky grips if you will. The XD sub compact has like half a grip attached to the mag.

Since the magazine is so important to the feeding of the pistol, are there any thoughts or experiences on the effect of hand pressure on these extensions? Can your grip move the thing around so that reliability deteriorates? Obviously the better made/designed the pistol and mag, the less of an issue but I am just wondering what in the real world people are expriencing here.

Thanks

No, with the modern designs, hand position or grip will not hurt anything.

The worst problem I ever had with them was the early Glock +2 extensions.

When you dropped a loaded mag on the floor or ground, the extension would pop off, and the mag puke it's guts out!

I understand they work now, but I still don't trust them due to the initial experiance I had.

Only in one other regard...Reliability in presenting your pistol from your pocket. Mag extenders are "snag-city" and are frowned upon by many, including myself. Most pocket pistols today come with two mags: one for the range so your little "pinkie" can jump in on the action, the flush mag for carry...

A Pearce +1 extension I had for my Glock 27 made it FTF on the last round. Probably due to reduced spring tension.
