I briefly freaked out when putting in an Apex trigger kit looking at the same thing... I thought the frame had cracked when I was driving the pin out.
It was a great relief when I looked closer.
I'm thinking of dwell time the same way and I'm thinking the change in the geometry of the lugs that gives a longer dwell time takes a bit more power to cycle. Does that make sense?
Certainly it's design specific, but isn't dwell time limited based on the how much recoil a given round generates? I'm thinking it takes more oomph to cycle with a longer dwell time.
I did some googling looking for other input on optimal barrel length for auto pistols... did not find anything where others have sorted this. It makes a lot of sense to me.
This seems to say for a given round, there is some maximal or optimal barrel length that allows the bullet to clear the...
Second trip to the range with the Apex SDI barrel. Ran well, which is good, because the first outing was less than great. I had left it a bit tight and was getting some FTE. It got better as I ran the gun and after just a tiny bit more filing seems good now (100 rounds without a hiccup).
Can't...
Got this in after about 3 hours... took it slow and needed to take more off than I expected based on the video (muzzle and the bottom fitting pad). This is a newer CORE, I wonder if S&W tightened some tolerances?... that said the stock barrel was a pretty loose fit.
I have a CORE with an Apex trigger / sear kit. IMO that kit really delivers and after lurking on this thread a bit, I ordered an SDI barrel and look forward to getting it to the range.
S&W should build these (at least some of them) this way in the first place... in the meantime, I am glad there...
