- Two interchangable backstraps
- Rounded trigger guard
- Extended "beavertail"
- Round magazine catch button
- "Improved" checkering and "rail system"
- "Higher grip angle," which I imagine means that you can get the web of your shooting hand up higher on the grip
- Round mag catch
- SF trigger housing
- Two grip backstraps
They have it listed at $199.99, which I don't think is too bad really, considering that Glock will not sell you just a frame, without the side and barrel and all the rest of the pistol. May be something to look into if you like Glocks, but your hands are too small for the Glock grip frame. From the thread on GlockTalk, it sounds like they will be releasing compact frames, and large 10mm/.45ACP frames sometime in the future.
