Possibly an Incorrect Posting by OP:
I can't tell if the Optics Planet posting is incorrect. Item description says that this extension can be used with g19 magazines. However, the Title has "9/40". I don't have a glock 9 or 40 or even know if they exist.
Reviewed using g17 and g19 magazines:
Retaining lips on the extension aren't designed well. The lips that keep the magazine retained, are machined with an outward taper. This causes the magazine to shift around in the extension. Ruined the basepad lips on 2 of my OEM g19 magazines. The extension ate away at the magazines and after 2 range trips the extension finally worked itself free causing live ammo to come out of the mag. Would not buy again. I know this is either a design flaw or and incorrect posting because I bought 2 and both extensions are the same. Both magazines using these extensions came free at the range as well.
Unfortunately, I believe I am outside of the return period so returning is a no go.
Pros:
good machining
Coated Well
Cons:
Bad design
Bad Magazine Retention
Possibly an Incorrect Item Description
Would recommend: No
