I was able to get out this morning about put about 400 rounds each through these . A couple of observations regarding the RDS equipped G19:
- Drawing and indexing on the RDS rather than the tip of the front sight post took some work. After a couple hundred rounds it felt natural, but it will take some continued practice to hammer it home. I did catch myself of a few occasions needing to search for the dot, but it can be overcome with time.
- The combination of the RDS, KKM Barrel and TBRC Micro Comp make for a very soft shooting, VERY accurate pistol. At 7-10 yards it was printing a single hole shooting slow fire, and at 15-25 it was a respectable 4-5 inch grouping. Admittedly, my pistol skills need some work, but I was more than pleased. This combination made follow-up shots, controlled pairs and failure drills easy to accomplish.
- The addition of the TBRC Micro Comp did not impact the reliability of the pistol whatsoever. I shot everything from 115-147 grain, including my carry 147g HSTs without issue. I had a single FTE/Double Feed around round number 210, but nothing prior, or since. I have an additional 15lb Tungston RSA on order to see if it makes an difference in felt recoil or reliability.
- I did not suffer the RDS flicker or loss of dot at all during this range trip. During assembly, I did make sure i slightly bent the RMR contact points, used Shoe Goo on the battery and sealing plate, and properly torqued the RMR screws. The RDS was easy to track from target to target and made accuracy simple. If anything, I found myself over-analyzing the use of the RDS and could have easily gotten combat effective shots off much faster than i did.
Overall, I am pleased with the set up, and will probably be sending the frame off for a little work shortly. Nothing too extreme, but at least a trigger guard undercut to eliminate the pressure from the "glock-knuckle", and perhaps some light stippling as the Gen 4 grip texture suits me just fine. Looking forward to getting it out some more over the next few weeks.
