I like my Shield a lot. But for running or biking, I really prefer something with a bit shorter a grip like the G43 or Kahr PM9. If you're in my area, you know where I live, I'll be happy to loan you each to try them out. A father in law loan is pretty hard to beat, though.
Thanks for the offer, but ended up picking up the G43 today after a couple of LGS visits. I agree it best fits what I was looking for. I think the video that sealed the deal is the M&P shield vs G43. The fact of adding a Taran tactical +1 and it being still shorter than the shield had me sold.
After picking up the G43 I gave her a quick clean & lube , and headed out to shoot. I put a box of federal 115gr range/practice through her as well as 20 rnds of 124gr Federal Hst with no issues.
After a few shots I was able to get a feel for her and get better shot placement. All shots taken at about 7 yards, including the 6 at the upper right little silhouette.
Now for the extras.
Of course the OEM sights have to go. Next after seeing the video I ordered a Taran tactical +1 and +2 extension to get capacity a little better. Also on order is a Talon grip to help secure her when She gets sweaty. Once everything gets here I will give her a workout test(unloaded) with my eliptical and try drawing and acquiring target when out of breath and sweaty. I will repeat this test at the farm I shoot at with a 400 yard run to target and then firing a few drills.
I will update after some testing and my first run with her.
