ALL NEW DESIGN!
TF went back to the drawing board and redesigned their SIG +20 using the successful "Goliath" concept (see our Goliath +20 and +30 for Glock-mag-fed carbines). To get there, we had to re-think everything, and added a custom follower!
You get:
- Quick-release base for easy cleaning
- "Sword-like" grip = No-slip control
- +20 rounds (50+1 capacity!)
- Rigid clamping design absorbs abuse
- CUSTOM DELRIN FOLLOWER
- CUSTOM MAGAZINE SPRING
- CNC machined from bar stock

Very happy with this product. Have not yet had a magazine related malfunction with this installed. Came with everything needed to install including the spring. Plan on down-loading your mag if you plan on reloading with this mag, its is VERY difficult to lock it in on a closed bolt with the mag loaded to full capacity.
It's nice. But only good for 47-48 rounds
This is a pretty nice extension. Pros: - larger than Taran - easy installation Cons: - won't load all the way to +20 (only 47-48 rounds) - the metal finishing prior to anodizing is non-existent. Can see all the milling marks. Should polish it properly or bead blast. A decent value for what you get and absolutely necessary for outlaw stages or 32rd empty start field courses (so you can download a bit)
