Howdy folks,
Yesterday my shooting buddy and I were able to venture out to our desert "range" and enjoy a long, but hot day, of shooting. While we still had the desire, we found as the day grew hotter we both felt we were beginning to simply waste ammo as our performance began to drop off. It was 107F here yesterday, with very little shade on our desert facility, lol.
One adjustment living here requires from the east coast, the day grows hotter as it progresses, with the highest temperatures at about 1800 (versus noon). We managed to get an early start, setting up at about 0800, but finally had to give up about 1400.
Earlier this week I had returned from a very pleasant meeting with my CZ gunsmith, who had worked his action magic on my 75B in 40. He had also done the same to a 9mm SP-01 which he then sold me. These two pistols are essentially the same, with the SP-01 having a slightly different grip shape, a full dust cover and a tactical rail. Both barrels are 4.7", with both frames made of steel. Both pistols were purchased in the DA/SA mode with manual safety. This set up allows a DA first shot (if the hammer is physically lowered safely), or standard cocked and locked carry.
I decided with the heat issue, I would only attempt to chronograph factory loads, and leave my handloads for another session. So starting with the 40 S&W factory loads these were my results:
Two groups of 5 rounds each were fired, with the chronograph set up 10' downrange. The two groups will be listed and then averaged. I simply round up or down to simplify the numbers listed.

Hope this information will prove helpful to some folks anyway. Those with a CZ 75B type pistol or a clone, may find it the most useful. Next time out to our desert "range" I will try to spec some reloads in both calibers. Who knows, maybe by then I will have a functioning 357 Sig barrel that will fit into the 75B 40 too.
I did finally receive my 357 Sig Bar-Sto barrel, but my gunsmith was able to confirm the semi-drop in barrel was anything but, and would take some serious fitting. He was about to leave for another match, and we agreed if I could not find someone to fit it locally, I would bring it back up to him with my pistol and some ammo. To be candid, I am hoping EFK Fire Dragon will have their 357 Sig barrels out very shortly, as theirs are truly straight drop ins. Then I can have the Bar-Sto fitted down the road.
