Picked up my new Solo STS from a local FFL today. Took her home, cleaned and lubed and her, then headed to the range.
I started my practice session with 100 rounds of Winchester Q4318 124gr FMJ. The Solo ate all rounds, with one FTF which actually looked to be a dud round. There was a primer dent, but no fire. The other 99 rounds shot just fine, and accuracy was good. Next up, I used 50 American Eagle 124gr FMJ. Same story, the Solo fired 50/50 with no problems. Accuracy was good. I then proceeded to test my carry ammo through the gun. I shot 25 rounds of Speer Gold Dot, both 124r and 147gr through with no issues. Accuracy was spot-on at 10 yards. Overall, my groups were about 3-4" at 10 yards. I am a relatively new shooter, and I think that as my skills improve, so wil the groups; a range officer shot 10 shots at 10 yards, all either bulls-eyes or very close, so I know it's me. Reliability, aside from the single FTF, was 100%. No jams, double feeds, FTEs, no issues of any sort. Recoil on the little gun wasn't too bad either. My other gun is an XD40 and I would say the Kimber had less felt recoil. My hand did start to get a little sore at about round 150, but I think that's to be expected from a small gun shooting high-power loads.
Overall, I am very satisfied with my Solo so far. Only time will tell how it holds up, but if the first 200 rounds of mixed ammo are any indication, I think this should be a great gun.
As a side note, I did break the gun down to clean it after firing the Winchester stuff. My hand was starting to sting and I wanted a break. That ammo is FILTHY. The inside of my gun was COVERED in black soot. When I cleaned the gun once I got home, at which point it would have had 50 Am Eagles, and 50 Gold Dots, it was nowhere near as dirty. Just a thought.
