I purchased a new XDm Compact 3.8" 9mm this weekend and took it to the range yesterday for a little break-in. I started off well with a 1" 5-shot group at 7 yds, but accuracy quickly dropped off after that. I'm sure the drop off was due to the shooter, not the gun.
I shot 100 rounds at 7 yds and 100 rounds at 15 yds. At 7 yds I could hold a 3-inch group fairly well, with a couple fliers. At 15 yds, I held about a 6-inch group, which is far below my expectations. I'm a pretty new shooter, and after the first 30 rounds or so my hands got shaky for the rest of the session.
I have mixed feelings about the gun. The gun performed well and I didn't have any jams or fails; however, I have a few issues with the grip, weight, and trigger, and I could use any tips you can provide.
First, the grip feels a little narrow for my hands. I have the medium backstrap installed, and once I wrap my right hand around the grip, there isn't much grip left exposed for the meaty part of my left thumb. After shooting a string of 10-15 rounds, I'd notice that I was supporting the gun almost entirely with my right hand, and my left hand was basically just there to have some place to put it. I'll try the large backstrap (I'm disappointed it didn't come with the tools to switch them out), and see if it helps. If not, does anyone have any suggestions for adjusting my grip or accessories to make the grip fatter?
Second, it was really hot yesterday, and I was shooting in 112 deg. (in the shade) heat. My hands got sweaty quick, and the hard-rubber/plastic used in the grip got slippery. Again, any suggestions?
Third, I could use some tips for dealing with the muzzle flip. I place my hand as high up under the beaver tail as I can, and I try to use a push-pull grip. The muzzle still flips quite a bit. I need to get to a range that allows rapid fire so I can see if the flip is enough to affect follow-up shots, but can anyone provide tips for keeping my wrists locked better? I learned to shoot on my friend's glocks, and I wonder if the more aggressive grip angle helps me lock my wrist better. I know the XDm has a higher bore-axis, but I was hoping the heavier slide would counteract it a little.
Finally, I bought the XDm based on a good rental experience with an XD9 with a great trigger. My new XDm's trigger seems to 'hang up' a little during that last little portion before the break. I don't want to pay for a full trigger job at this point, but I may try to polish the sear to see if I can smoothe it out a little. As a noob, it that something I can do myself, or do I really need to take it to a pro?
One final comment. This gun is heavy. I knew that when I bought the gun, but I hoped it would help reduce recoil, and I also hoped the weight wouldn't be that much noticeable when holsterred IWB. The latter remains to be seen, but I'm also a little worried that the extra weight added to my fatigue and shaky hands after only the first 30 shots or so.
I hope to take the gun out with my friend's G19 to compare the two side-by-side. As of now, I'm having a little buyer's remorse about the XDm, and I'm wondering if I should have bought something a little lighter with a thicker grip (G19 or M&P).
Thanks in advance for the comments and advice.
