That is a terrific collection!  I have always been a tremendous fan of the 10mm cartridge and was an early adopter, buying (new) one of the first Colt Delta Elite pistols ever made, in 1987 or so.

In 1990 I had it customized a bit, fitting an oversize barrel link for tighter lockup, and the Wilson Shok-buf full length guide rod system. I also had them relieve the ejection port. 

I shot it that way for years, then last year I sent it to Wilson Combat to have them fit one of their triggers and give it a proper trigger job. 

Just in the past few weeks, I was able to buy long-discontinued NOS Pachmayr rubber grip safety, arched mainspring housing, and Pachmayr grips. A local gunsmith fitted them and also polished the feed ramp a bit. I just got it back a few days ago, and haven’t fired it since this last round of improvements. It certainly feels much better in my hand than it did with the old slab-side grips and flat mainspring housing. 

When I am doing my part it has proven to be extremely accurate. The photo below shows one of my better groups at 15 yards with full-power ammo (10.0 gr Blue Dot and 180gr lead SWC).

(Edit—the forum software won’t let me upload the pics of the target or modified magazine for some reason)

However I find I often have failed to do my part, due partially to the former trigger pull, and partially to the stock grips.  It was harder to consistently shoot it well than my softball Gold Cup 45. 

I’m looking forward to my range opening up again so I can try it out. 

I recently bought a pair of CMC 9-round magazines. While technically they (barely) held 9 rounds, the internals were so compressed that they could not be inserted into the gun with the slide forward. They only fit when the slide was locked back. 

Taking a cue from my Detonics 45, I had a friend mill slots in the base of the mags, which allows the back of the follower to just barely protrude and gives the necessary internal clearance to let them be installed in the gun with the slide forward. 

10mm (when loaded to proper 10mm pressures) totally rocks!
