Back in the summer, I got my wife a 365 Spectre Comp and a EPS Carry. We didn't spend too many sessions shooting it, but at 25 yards and further, it struggled with accuracy. Ever since the 365 Macro came out, I have been wondering about accuracy at distance, but haven't seen reports. I recently picked up a 365 Macro, and last night installed a 407K, which I rough zeroed with a Wheeler green laser sighter. Generally that gets me within an inch or two at 25 yards.
After shooting my Open gun and a Glock this afternoon, I got to shoot the Macro. My initial impressions were that it was a great shooting pistol. After 50 rounds or so of AE 124, I decided to check the zero on a USPSA head box at 15 yards. It seemed like my group was wandering in windage, and I ended up making a number of adjustments without getting a satisfactory zero. I changed to Lawman 124, thinking the American Eagle was a problem, and got the same result. I then painted an eight inch steel at 25 yards, and was using the whole steel.
I asked my wife to shoot it, as she often shoots better groups than me. Also, the 365 is her EDC and she competes with a 320, so she is very Sig centric. At 15 yards on a head box, it was as if she had two groups with elevation fine, but windage the issue. At 25 yards, she couldn't keep all five of her shots on the head box. I painted the steel, and she was using the entire eight inch steel, with a pattern not a group.
I painted the steel again, and shot Lawman at 25, getting this group which was similar to what she was getting.
Disgusted, we decided to take the 365X slide off her EDC, and drop it on the Macro lower. I shot a quick five shot group at 25 and got this.
Unless we got two very unlucky uppers, I believe Sig has a problem with the upper on the Spectre Comp/Macro pistols. I really like the Macro grip module and magazines, but no way am I carrying that upper given how well the 365/365XL/PMM barrel and comps shoot at 25 yards and further.
