This P365 is a snappy little devil. I am feeling it in my right forearm. I really like the sites and it seems to be very accurate. I did not shoot at any paper, which I will do before settling on carry ammo. I did notice variation in POA/POI between different bullet weights.
Prior to shooting I took down the gun and it was wet with oil, no sign of shipping grease, so I just took it out to the back yard range.
I shot 150 rounds of Blazer 147 TMJ aluminum cased ammo. 100 rounds of American Eagle 124 round nose brass cased. 50 rounds of Winchester White box 115 round nose. 50 rounds Speer Gold Dot 147 hollow points, 50 rounds Speer Gold Dot 124 hollow points. Also 17 rounds of mystery 115 hollow points I had stuffed in a Beretta mag. All rounds were fired standing at 12-15 yards at steel plates.
I first shot 50-60 rounds of Blazer and noted that I had to hold on the top of the 6" steel but could hit it consistently if I concentrated on my shots. Shots on the 12" steel plates were gimme's as long as the front site was centered on the plate.
I next went to the WWB 115 and they were laser beams. I went 10 for 10 on the 6" plate, and switched to the kiddo's .22 rebounding plates 3"wide x 10" tall and still hit consistently. I barely shot at the big plate at all.
The 124 AE was hard to figure out where POA/POI was. I have not shot much of this at all and have no real comparison in my other 9mm, at this time, to figure if it is this ammo or this weight. I was quickly frustrated with more misses than hits unless I went to the big plate.
I then decided to see if mixing ammo in the mags would induce a failure to feed or eject, so I dumped the 17 115 HP, 10 each of the other hollow points 147 and 124, and 10 each of the FMJ's in a bag and mixed them up. I closed my eyes and grabbed a handful and loaded up with out looking to see what went in the mags. I just shot at the big 12" plate and had no failures of any kind. If I waited for the plate to slow I had no misses, again at 12-15 yards.
By this time I had fired approximately 300 rounds and noticed that my accuracy was falling off. I was starting to flinch and jerk a bit. I took a bit of a break and rounded up the cases, I tried to pay attention to where cases were grouped and if there was a difference in brand and bullet weight. I was moving around a bit, and some of the cases are the same despite brand and bullet weight, so no real conclusions. I did not remember to look for primer drag until I sat down at the computer, so will have to walk back to the range to check on that.
I finished with about 40 rounds of each of the GD's, and 20 or so of the 124's and 147's. I noticed that it was much harder to keep the 124's whether round point or hollow point on the steel, compared to the 147's hollow or round.
For what ever reason the gun or I seemed to prefer 115's or 147's over the mid weight 124's no matter bullet shape. I am going to do a thorough cleaning and slipstream job on it later tonight and will likely do a bunch of dry firing to work it in. I need to dig into my ammo stashes to see what else I have for 9mm. I want to try some other brands and bullets to see if that makes a difference in how this beauty shoots. I also need to get some paper plates out and see what the groups look like, now that I know it functions.
