Thanks for the additional thoughts.

Also, thanks for the tip about magazines.

I've noticed that there are quite a few of 6 round 4513/4553 mags being sold as CS45 mags. The CS45 mags have the extra indentation up top to help the rounds stay put during recoil. I have a pile of the 4513 mags now.

May grab this CS45. Still trying to nail down a good price...again, one mag, blued, some carry wear, no box, etc. I have some thoughts about it but welcome any opinions.
