I had the same question 3-years ago. I ended up asking Brian for a recommendation on which was best for dot use. He stated clearly that the Gold were better for dot use. I use a green dot and it really "pops" when I am aiming.
This wouldn't be acceptable/legal. Was discussed during last year's PCC/CO Nationals with Troy. The pistols you mentioned have the thumb ledge incorporated into a non-OEM replacement slide stop.
Recipes for Major PF using e3 reloaded for my CZ Tactical Sport
1. 180g ibejiHeads, 3.8g e3, range brass, Win SPP PF = 171,180
2. 200g Bayou, 3.3g e3, range brass, Win SPP PF = 166,587
I've stuck with a 115gr Berry's or xTreme bullet for both short 5.25 and long 14.5 barrels. Always a good feeding profile at 1.125 inches with appropriate powder loads to make Power Factor.
I have three 170mm tubes with either a 3 or 5-inch extension that I ran last year for USPSA PCC matches.
They ran without a single misfeed or any other mag related issue. They don't swell when fully loaded as my Glock would do. So far there has been no wear and tear on the feed lips nor the catch slot. No tuning required. Performance is just as advertised.
YES, they are expensive but, I routinely would have to toss 2 Glock 33-round mags each year due to too much wear, bulging...etc.
For me it was a solid investment.
Your mileage as they say, may vary...

Completely agree. I just turned 62 and have these:
