    I'm looking to extend the magazine capacity in my Glock 33 Gen4 from 9+1, to one extra round to 10+1. This kind of capacity extension usually only adds about 5/8" length to the grip which is as long as I prefer to go. (Or, if it works in your gen4 model 27, it should work in my gen4 model 33)

    I figured maybe you guys can provide the distributor or link for the one which has worked reliably at the range for you.

    IMG_0088.JPG IMG_0087.JPG IMG_0089.JPG I've used Pearce extensions for 20 some years. Get the Pearce XL (pg39) extensions. They are actually +2. You can order through most Distributors, anywhere from $7.95 to $9.95 a set. Glockmeister.com is one.

    Ps I have these on (40) mags and have used these in competition as well. The extension fits 26/27/33.
    If the plus 2 does not excite, they have plus 1 and zero extensions as well.

    Example of the Pearce +0 extension on my G33 shown below...it doesn't add capacity, but it does add comfort:

    The Glock OEM extensions have always worked the best for me.

    Pierce extensions are great. Use the on most of my 27/26 mags. I have oem extensions as well on several others. X grip on a 23/19 mag is awesome when able to pull it off. Don't forget GAP floor plates when Max conceal is desired.

    The Glock +2 should give you one extra round in the 357/40. It's usually +2 in 9mm.

    The old OEM extensions marked "+2" added +2 rounds only for 9x19mm magazines. That part is obsolete and no longer made.

    It was replaced by the extension marked "+" which adds +2 for 9x19mm, .357SIG, and .40SW. Both extension part 7151 and insert 7165 must be used together. This is the only extension I use on some of my G31 magazines ... one can not go wrong with OEM parts.

    Aslan, are you sure that the Glock OEM extensions always worked best for you? I'd feel more assured if you posted it a 4th time. LOL Thanks.

    Mike-M,
    I'm not sure how these parts work. I'd appreciate your input.

    It seems like these two parts are included for the $7.99 Am I to understand that these two parts are all I will need along with the original model 33 magazine, and the spring inside of my magazine?
    Don't you hate when you order parts, wait for them to arrive, and then find out you need other parts too.

    I tried adding mag extensions to my G33 and discovered that I much preferred a G32. Almost the same grip length and much more. Why buy the smallest gun then add size instead of going to a mid-size to begin with?

    There's an echo in here! :)
    That's all true. That's all you need.

    I'd had my eye out for a Glock chambered in .357sig for some time but their popularity in these parts seemed to be zero, and already having a .357sig conversion barrel for my G20 had me desiring a smaller model. I hadn't originally planned on purchasing a G33, but one day I happened upon one in a local pawn shop...it was in their "used" section but appeared to be NIB unfired with not a single mark on it and complete with everything it came with (including the original bill of sale for $490 +tax), for $375 out the door. I simply couldn't refuse or let that one pass me by.

    I have large hands so I immediately looked into mag extentions and found a Pearce model for the sub compact G26/27/33 series Glocks to be readily available. The +0 mag version doesn't add any appreciative length to the gun nor make it any less concealable, it just adds a place for my pinky finger to rest and contribute to a more positive grip. I always carry a spare mag, so 9+1+9=19, and I've said it before that if I can't get it done with 19 rounds of .357sig I need to seriously reconsider carrying.

    You can run the flat base plate for better concealment on the SC and use the other mags with the extended base plates as backups.

    I use a clip-draw to hold my pistols in my wasteband and keep them from sliding down into my crotch. I don't like wearing my shirt tails out in public, so I pull a loose long ruffle of my shirt to drape over my pistol butt to hide it. Therefore, the pistol butt must be short. I regard the Glock 33 and 27 as little barking Chihuahuas and have no problems gripping them. The extension is mostly to add one more round to 10+1.

    I did not realize the updated "+" extension would give you +2 in the 40, I'll have to try and shove one extra round into my + mag when I get home.
