Taylor Freelance Walther PDP Full-Size Middleweight Kit - Black

Kit includes:

Brass Backstrap
Aluminum Magwell
Two +3/+4 aluminum basepads
Kits adds 6.95 ounces of weight to your firearm

The TF magwell for the PDP offers a sleek, cost-effective way to get the most out of your pistol. Combined with the TF metal backstrap, the system:

lowers the center of gravity (for better handling)
increases mass (for softer recoil)
makes reloading much easier.
Choose a weight level to fit your needs. If you're carrying this gun every day, the "lightweight kit" is the way to go. If you like a smooth-handling pistol, the all-brass "heavyweight" offers MAXIMUM control. The "Middleweight" kit might be the most-popular of all. You get the recoil-calming and balance-correcting weight of the brass backstrap, a less-costly aluminum magwell, and lightweight aluminum basepads (reducing total weight on your belt).

Few modifications NOTICEABLY change the way the gun feels/acts -- these kits are one of the few.
