Bill H Posted October 17, 2021 Share Posted October 17, 2021 I found with 21 rd mags and TTI extensions I can get 23 in 2 out 3 USA marked mags and only 22 in mags marked Italy. Maybe that is why some have problems. Italian mags a hair tighter? Link to comment Share on other sites More sharing options...

They are also reloadable. I get 23 in the Stoeger mags. Also reloadable. Link to comment Share on other sites More sharing options...
Bill H Posted October 19, 2021 Share Posted October 19, 2021 The 2 USA made mags I get 23 in do not have Grams kit. Just lucky. Guess I should try one. Does the slide lock back with the Grams follower? Link to comment Share on other sites More sharing options...

I bought a Gram spring and follower abs it must be catching on the baseplate. Link to comment Share on other sites More sharing options...

Butterpuc Posted November 20, 2021 Share Posted November 20, 2021 (edited) Do you let the springs rest in the bottom of the +1 base pads? Edited November 20, 2021 by Butterpuc Link to comment Share on other sites More sharing options...
Philip Dedmon Posted November 21, 2021 Share Posted November 21, 2021 I have 12 21 rd. magazines all marked Made In Italy. I'm also using the TTI +1 Base Pad on all 12 and the Grams Spring/Follower in just 3 of them that will hold 23 rds. When I installed the Grams Spring/Follower Kits in the 3 I loaded them with 20 rds. left them for a hour or so, added 2 rds. left them for a hour or so, added 1rd. and left them loaded with 23 for 2 days. All 3 are working great. I can reload with them but hardly do so. Link to comment Share on other sites More sharing options...
Butterpuc Posted November 23, 2021 Share Posted November 23, 2021 (edited) I have TTI base pads on all 3 of my Carry Optics pistols. M&P CORE, Glock 34 MOS, and now Sig P320. The Sig mags are much much much harder to get 23 rounds in the magazine. The M&P is by far the easiest, with 23 rounds in the magazine, you can still compress the rounds another ~2mm, super easy to load. The Glock is still way easier than the Sig, once there are 23 rounds in the magazine, you can just barely compress the rounds by maybe 1mm. With the Sig magazines, I had to press harder than ever to get the 23rd round in. I can get it to load in the P320 on a closed slide, surprisingly with ease, but I have not had a chance to see how well the gun functions with these mags loaded to 23 rounds. Forgot to add these are 21 round magazine tubes with +1 TTI basepads. Currently, I have 3 P320 mags loaded to 23 rounds just sitting in the safe, I hope this will help.

RangerTrace Posted November 10, 2022 Share Posted November 10, 2022 So, USPSA is low on my priority list these days, but how often are you at a disadvantage with a stock 21 rounder? I have to assume in the stock configuration, it is ultra reliable?? I have a bunch of 17 rounders for IDPA and several 21 rounders for work. I was going to order another half dozen to be dedicated USPSA mags...... Link to comment Share on other sites More sharing options...

I use a 21 rounder with an extension only on a stage where I'm not going to do a reload and the 2 extra rounds may be needed if I have a makeup.

I recently found out during a match with a stage that used 24 rounds. Used a barney mag along with my Sig 21 round mags with TTI base pads and Grams springs. (23 rounds loadable). For those that have the necessary confidence, eliminating a reload definitely helps! And they fit the gauge with no mods........... Link to comment Share on other sites More sharing options...

RangerTrace Posted November 11, 2022 Share Posted November 11, 2022 Sounds like I need to build one extra capacity mag, just in case. Link to comment Share on other sites More sharing options...
boudreux Posted November 12, 2022 Share Posted November 12, 2022 I put Henning basepads on my 17 round x5 mags and am able to load 23 using an uplula fairly easily. Stripped the first round off fine. Did not try 23+1 to see if if would strip and feed fine but I will do that next range visit. Link to comment Share on other sites More sharing options...

X5SigChris Posted November 18, 2022 Share Posted November 18, 2022 I have all my factory 17 rounders with TTI plus 5s. They work fine but I mainly run the 21s. I personally find that I grab them better. So if at all possible I start with a 17 and reload with a 21. Maybe it’s stupid but it’s me Link to comment Share on other sites More sharing options...
RangerTrace Posted November 18, 2022 Share Posted November 18, 2022 I found the easy answer here....I just bought a complete rig from Grayguns... it comes with 4 22 rounds magazines. https://manage.kmail-lists.com/subscriptions/web-view?a=Ui5FJW&c=01EZA3JKGY7E9KXK32HBH4ZDQ3&k=0f96ff4af4ea7b12c7c163d4ba19770b&g=UVqJeK&m=01GHYT29NZQ7JDMK1QBWFKMKXK&r=UNMKUDx Link to comment Share on other sites More sharing options...
