3pc Extension Fits Glock Model 42 (.380 Cal) G42

This grip extension for the stock G42 magazine fits and works very well. The appearance matches the G42 grip so does not seem out-of-place. Color is very slightly different but this is only obvious with a photograph under daylight.Installation was not too onerous but there's a trick. I'd recommed using a vise to clamp the magazine down. Face the front of the magazine away from you. Use a 3/32" punch to press the magazine insert down just below the floorplate. (If you press too hard on the insert, it very likely will become unseated. Not a big deal but you'll need to remove the magazine spring to retrieve). With the insert depressed, tap the floorplate with a padded mallet until it loosens. It may take a couple energetic taps. Once the floorplate is released slightly (not fully removed), slide it forward while covering the insert with your thumb to prevent it flying out. Replace the factory floorplate with the replacement. Tap it back into place with the mallet until the insert button pops into place.If you had previously unseated the insert, remove the spring and fish out the insert and put back in place. The insert rides right on top of the spring when assembled (well, technically on the bottom of the spring when in use).If you don't have a vise grip this process is a little aggravating but certainly possible. One method is to place the magazine on the edge of a table, use one hand to steady magazine and depress the magazine insert follower, then tap off the floorplate with a padded mallet. Then replace as in the above.Once installed, this looks and works perfectly. It has just enough room for me to fit my entire hand. The fit is very secure, no wobble or extra play, and no feed issues. Keep in mind that this does not add any extra capacity. You'll still have 6 rounds but IMHO, the G42 without this extension is useless for me. I'm very pleased with this product and will buy again.

Perfect great deal.Works well

Perfect fit

Helps on the 380 mags

Overall, great product for the money. Fit well, although they are slightly different in cut to the original Glock grips. Look and feel nice, but are a pain to install. Not the company’s fault, this is on Glock. Again, overall great value!

what a difference

Great addition. Just what I needed. Packaged wellThanks will buy in the future.

My wife’s Ruger came with magazine extensions and I really liked the feel when I shot hers. My Glock 42 does not have these from the factory so I added these extensions and am pleased with the extra stability they give me. Very easy to install. Very pleased.
