I am at 150 rounds through the R9 tonight.
I had originally planned to put just a bunch of 124gr Gold Dots through the Rohrbaugh but I fired a different mix of stuff.
Mostly I fired 124gr Lawman. I fired at 15 feet and was really happy with my 7-dhot groups. I only fired 28 rounds of the Lawman I fired 7 rounds of 147gr Gold Dots, 7 rounds of 147gr Winchester Ranger T, and 3 rounds of 147 gr PDX.
When you add in the 5 rounds of 124gr Lawman I tacked onto my last range trip - it's 150 rounds through the R9 without a problem.
I know you're suppossed to get through 200 to 250 rounds with a pistol before you trust it for carry, but actually I do trust it for carry.
One thing I noticed though is that using 124gr Lawman TMJ, I had very tight 7-shot groups, but as soon as I switched to 147gr ammo I had 3" shot groups. At 15 feet that's not good IMO. It was the same with Gold Dot, PDX and Ranger T.
I made sure my grip screws were tight before I moved to the 147gr cartridges.
I have 147gr Lawman TMJ, I'm going to use some of those next range trip, I'm also going to shoot my Winchester Ranger T at the beginning of my shooting session - not the end of it.
