Congrats on the KSP 4566! I am always watching out for one of them to come up for sale.

The main differences between a PC 45CQB and a 4566TSW are the 4 inch match grade barrel - which has no bell mouth at the muzzle and wont work in any other 4566 - and the Briley bushing which holds the muzzle tightly to the slide.

Other than a few other cosmetic differences, the PC 4566 and the 4566TSW have a few things in common. After all, the TSW series guns incorporated engineering advancements pioneered by the Performance Center.

The oversized frame rails and delayed unlocking being the major common trait. The oversized frame rails (being hand lapped on the PC guns - NOT on the TSW series) contributing to tighter slide to frame fit and increased durability. The delayed unlocking contibuting to less felt recoil and increased accuracy.

Most of the parts used in the PC 45CQB are interchangeable with the 4566TSW. A good gunsmith (BMCM ) might be able to put a trigger on a 4566TSW which might rival or surpass a PC trigger.

Anyways, your KSP 4566TSW is a fine pistol in its own right and might be considered by many 4566 aficionados to be a contender for the "Ultimate 4566" title itself. Regards 18DAI
