Bowie HK P30S w/ Delta Point Update

Well we were off to a rough start. The original Delta Point died before I had it fully zeroed it. Leupold replaced it without question.

I installed the replacement unit and set to sighting it in and had some strange trigger issues that I have attributed to the altered slide geometry regarding the firing pin block channel and the "heavy" firing pin block spring. It seems that there was to much tension on the inner workings of the gun and the firing mechanism was binding and the gun would intermittently not go bang. I happened to have a "light" firing pin block spring on hand and tried that as a quick fix and lo and behold my problems went away.

Previously before the original dot died, I had ran the gun in a couple of matches with tape over the emitter and used the back up iron sights. This time I was able to compete with the sight active and I was floored by my level of improvement in almost all areas. The one issue I'm having is picking up the dot during my initial press out for the first shot on target, this just requires more dry practice of mounting the gun and building "muscle memory" ( I hate the term, only because there's always going to be the one guy that says "muscles have memories") in order to replicate proper draw stroke and apply it correctly. In order to do this I need to get the gun a little more up and my head a little more down....

Like Dave Bowie as seen in this picture.

This optic really does wonders with my eye dominance issues by bringing target and sighting into one focal plane*2. So instead of having to look at the target, look at the front sight, look at the rear sight, look at the target etc. I just look at the target and place, in my case the triangle on the target and press the trigger. One little oddity is that to get the optic zeroed, I have the windage almost all the way to the left, I attribute this to my severely dominant left eye.

I have a Glock 17, 2nd Generation on it's way to Bowie for him to work his magic on with some of the same things I had done to the P30. Not sure if I'm going to stick with the Delta Point or go with a Trijicon RMR, Dave currently prefers the Delta Point due to the fact that it keeps zero better than the RMR but the RMR is supposed to be more rugged....Suarez has been doing a lot of work with the RMRs in the last couple of years as well as some others, currently Hilton Yam of 10-8 (their blog is now Modern Service Weapons) has a test going on now with several RMRs and the results are not that impressive but he has been in contact with Trijicon and they are to be improving the RMR to make it more rugged.

I am now on my fourth RMR since starting the project at the end of August.  The first three have failed as follows:
  • Adjustable intensity RMR07 died after 1185 rounds, with the dot turning on/off intermittently. Thanks to painted witness marks, it was easy to see that the windage adjustment screw was also rotating 2-3 clicks every 50 rounds or so.
  • An automatic intensity RMR02 suddenly lost zero after only 625 rounds. The external elevation adjustments had not moved, but the point of impact shifted down about 24″ at 15 yards.
  • A second automatic intensity RMR02 (below) lost zero after about 750 rounds in the first day of a class.  It was off by about 6″ at 15 yards.

Dave has said the same regarding Leupold and the Delta Point and ongoing improvements. Not sure which way I want to go. Good news is that I have some time to think about it as my gun won't be ready till near summer of 2013 so I have some time to evaluate the Delta Point some more before making a decision. Maybe by then we'll see some real progress from either maker, but currently I'm pretty happy with this package.
