Mag extensions, 17 to 23 round. Springer vs Henning.

[Speedwagon]

I purchased some Springer Precision mag extensions to increase my 17 round Sig mags for my P320 X5 Legion and with the extensions I purchased the Grams Extra Capacity Kit to increase my capacity to 23 instead of 22 for USPSA. I can get the 23rd round in the mag but I really have to work at it. If I top off and have one in the chamber, after I fire the first round it has problems stripping the first round out of the mag and it won't go into battery. I'm using a 12# recoil spring and would rather not go to 14# just because of this because it runs fine otherwise.

I'm wondering if it would work better if I bought Henning extensions and used the Grams Extra Capacity Kit with them I would get a real working 23 round mag.

Is anyone out there using the Henning extensions with the Grams Extra Capacity Kit and getting a full 23 round mag capacity and the gun still runs fine? I'd just like to hear from people that actually use them before I spend the cash on them instead of just believing what they post on the web site like Springer did.

Thanks all...happy shootin!

I'm running Henning extension with exactly your setup, can fit 23 rounds no problem. I can squeeze 24 but you may run into reliability issues.

I also run a Henning extension with the Grams spring and follower.

Runs 23 rounds no problem.

Sounds like I need to try a henning setup for 23rds. At least one magazine.

Thanks for the replies people! I ordered three of the Henning extensions.
