Thanks for the compliments. I must say it shoots as good as it looks too! I don't have a breakdown of the gunsmith costs (he supplied a good majority of the parts in the gun too) but there is a total of about $1600 invested in the Nowlin gun. I would glady pay more for the results I've experienced. I have a Wilson CQB that I love and paid a lot more for, but this one took the Wilson's place as my favorite.
The guide rod is one that Nowlin provided and installed. It is the two piece variety. The 10mm officer magazines are from Metalform. They are not cheap, but where else can you get them? BTW They function great.

This little guy now has about 500 rounds through it. I have had one FTF and that was because I limp wristed it to try and make it jam. It did.... I really am not a big fan of the rubber grips, but they do help you hang on. I compare firing this gun to shooting hot loads from a Glock 33 (357 SIG). It has some bark (and bite too!) Being a little heavier than a plastic fantastic, it doesn't recoil as much, but more than my .45 Officers ACP.
The Colt frame just went off to Tripp Research where it will be built into another interesting piece. This one will be a Hybrid barreled Colt Officer lower and a commander upper. It will come back wearing a nice coat of hard chrome. It too will be a 10mm. I'll supply photos once I get it returned (supposedly 6-8 weeks). It should be worth the wait.
