Cosby Posted January 31, 2005 Share Posted January 31, 2005 I put a Tac Star 8 round mag extension on an 1100CM (don't ask what happened to the original extension, it's a long story). I have tried various spring lengths but the thing will only hold 7 rounds. The 8th round almost goes in but not quite. Any ideas? P.S. Benny, the 40 you built for me shoots great!

ErikW Posted January 31, 2005 Share Posted January 31, 2005 For most extensions, the advertised capacity includes the chambered round. Link to comment Share on other sites More sharing options...
Cosby Posted January 31, 2005 Author Share Posted January 31, 2005 This is definitely a 3 round extension. Once in a while, I can, with a lot of force, get the 8th round in. Most of the time it lacks about 1/4 to 1/2 inch. 3 rounds drop into the extension with about an inch to spare. Link to comment Share on other sites More sharing options...
Sestock Posted February 1, 2005 Share Posted February 1, 2005 You will only be able to get 7 rounds in the tube no matter what you do. The 3 round extension only gives you 7+1. Link to comment Share on other sites More sharing options...

Carlos Posted February 1, 2005 Share Posted February 1, 2005 I disagree. You almost got the last round in. You are likely using the wrong length ammo. What?!?! Its all the same right? 2 &3/4" right? The length of 2 & 3/4 ammo in the real world is all over the place. S&B 2&3/4" slug: 2.442" Federal HiShok 2&3/4 2.364" Remington Reduced recoil 2.320" Fiochi low recoil Buck 2.325" S&B Buck 2.545" PMC low recoil Buck 2.455" Differences seem small but multiply those by 9 & you can come up short. When I bought my Winchester Super X2 & took it to the 1st club 3 gun (the unofficial match at NRA HQ) I was really disappoined to find that my "9 round gun" only held 8 rounds of S&B buck. I thought: "what the ***K?!?!" This gun was sold as holding 9 rounds of 2&3/4 & these rounds are not even close to that long. I simply had to switch to Remington. THere may bhe other fixes to the problem. But I wish the companies would come clean on actual shell length & gun/extension capacity. D. Link to comment Share on other sites More sharing options...
