+5 All Day Long!!

by

Love the design and feel of the mag extension! +5 on my Glock 19 Gen 5 just as advertised. Thanks guys, I will certainly purchase a few more from the Glock Store.

Provided Spring Extension Issues

by

The spring that came in the package for the extended mag for the 19 was to wide. Not fitting correctly inside the magazine. the factory spring is a little shorter but seems to be feeding fine even with the extension.

Quality looks good, packaging says +5/4 though

by

It says +6/5 on the site but the 2 gold extensions I received in the mail say +5/4. Did I receive the right one? I don't see any +5/4 on your site so I'm assuming it's just mislabeled.

Not meant for 10rnd magazine but will work with stock spring

by

This magazine extension is meant for non 10rnd magazine due to the 10rnd magazine spring being thinner, but as noted from the other reviewer....it will fit with stock spring and cycle properly.
