This should primarily only be a concern with 40S&W in a Glock.

This was discussed in another thread, and includes a neat picture showing 40S&W chambered in different pistols:

As long as you keep an eye out on your brass, particularly near the case head / webbing for 40S&W, you should be fine.


Also, given that 124gr is on the heavier side for 9mm, I echo Dan W's suggestion of keeping the longer seating and upping the powder charge by 5% at a time, staying under the max.

To continue to concur with other posts, a very low charge will indeed cause soot and sealing problems.  I have a bunch of low-charge Unique based rounds in 40S&W and lead that typically don't lock the slide back at the end of a magazine, are sooty / smokey and will reduce visibility to zero if fired in quick succession :).

Speaking of this, when shooting lead, I carry a bore snake with me in my shooting bag when I go to the range.  Particularly handy when developing a lead-based load to check fouling ... or when ya have a good load... for quickly running through at the end of a range session.  Doesn't replace a proper cleaning, but does help :).

I finally got a chronograph and made it out to shoot today. I made up a large batch of 9mm.  I used the 124g RN Ranier bullets with 4.65g of autocomp and OAL of 29.20.  They averaged around 1050 fps.  Cycles the G17 and had no issues. Decent accuracy at 25 yards.  I went ahead and put some factory rounds through the chrono and they were averaging around 1200fps.  I think I will up the autocomp a bit more and get some more readings. 
Dan, when you said you would load 4.8g, I think you may have been spot on there.
Additionally I need to find more autocomp somewhere or work up a new load with either unique or power pistol.  I may run out of small pistol primers before the autocomp though. 
Thanks again for the help/advice.
