Shot the 17 with the ACRO P2 this past weekend. I had the complete gun setup for over a month, but things just didn't align until this past weekend. Zeroed the dot and shot about 200 rounds. New gun with a recommendation for 200 rounds with the barrel that came with it. Flawless operation and decent results. Took me a bit longer than usual to zero the gun, but mostly due to some brain farts of moving windage when I thought I was adjusting elevations and vice versa. First impressions are I like the window of the ACRO P2, with a little more space vertically than the RM06. The size of the optic body didn't bother me, and it actually helps in some ways over the RM06. Will see how the mount (builder included CHPWS plate) holds up, but I don't expect any issues. Will be using this gun in a class end of May where the round count is in the 800-1000 round estimates.
The slide for a different 17 came back this past weekend too. I had that one milled for the Holosun EPS (K footprint). I wasn't able to shoot it, but mounted the RDS and installed Dawson FO sights. The optic cut milling was excellent. I would say perfect it with no slop front/back. In fact, the optic body took some light tapping with a hammer to seat well and once seated, the optic is not easy to move/remove. Good indicator that the contact between the optic body and the slide is solid, and connection not fully dependent on the mounting screws.
The slide window of the EPS is smaller than the ACRO P2, but I think sufficient. I had been shooting the EPS Carry on a 43x. While the EPS Carry is much smaller than the RM06 that I had gotten used to over the past many years. The EPS is slightly larger than the EPS Carry and I think good proportions to the full sized slide of the 17.
