the 38 special was designed for target shooters in the semi automatic version. Smith and Wesson 52 current price of 1k to low of $700. Colt 1911 were also made just for that purpose. Coonan arms made them even in 357 magnum but they were not target guns. 38 special in the target configuration is very accurate 1 in group at 25 and about less than 2 at 50. This will give you the edge in Bullseye shooting because of the low recoil. On rapid fire you can easily be on target.
If you have put together a 1911 45 you can easily convert your by buying a 38 special barrel from clark another 10mm slide and a magazine. fit your barrel to the slide and you have a complete upper in 38 special. The only thing about the clark barrel is you have to modify your frame for the ramp cut out. I assume you have a mill so you can do it yourself,if not send it to Clark and he will cut it for you .I don't know his current price. If you can find a 38 special barrel without a ramp you can do it without modifying the frame. Colt National Match guns doesn't have the ramp barrel. You can only shoot wadcutters into this gun. If you want a regular 38 special ammo, you have to find somebody selling a Coonan firearm.
