Because I'm an engineer, and because I dearly like data, (and because this is the best forum on the web... thanks Para...) I painstakingly went through this thread and pulled together a spreadsheet which summarizes the ILIF posts contained herein (and contained in this thread only). If you want your ILIF counted in the next update of the spreadsheet, post it as described in the opening of the discussion. I may, at some point, look at other forum's discussions on the topic / dig through the numerous posts on S&W forum looking for distinct incidents.
My observations:
First and foremost -- sorry, I gotta say it...
A lot of folks would well benefit from reading the thread in its entirety before posting (pay particular attention to Osprey's original post reproduced below.)
All that being said, here's the data:
Total ILIF's: 20
S&W ILIF's: 19
Tarus ILIF: 1
Other ILIF: 0
Rated Caliber of ILIF's reported:
.32 H&R Magnum: 1
.38 Spl: 1
.38 +P: 2
.357 Magnum: 5
.45 ACP: 4
.44 Spl: 1
.44 Magnum: 5
.480 Ruger: 1
Number of ILIF's attributable to "hot loads"* by caliber:
.38 +P: 1
.45 ACP: 1
.44 Magnum: 1
Total: 3
My general observations having read all the posts in this thread:
1)It appears as though most of the S&W guns involved are lightweight J-frames shooting "normal" loads.
2)Lock or not is a personal preference. The general responses are:
"I ain't buyin' one."
"I bought one, but now wonder about reliability."
"I'll buy one and take out / modify the lock."
"I'll buy one and take my chances."
I will not enter this debate from any point other than a factual one. The facts are above.
I will, on a monthly (or so) basis, update the spreadsheet to add new, properly formatted posts on ILIF's. Please be nice and stick to the original intent of this thread. If you want to discuss the lock, please revive one of the many existing non-scientific, opinionated, threads threads on the forum.
*hot loads are subjective opinion (in most cases, I counted it a "hot load" if the round is near the rated capacity of the firearm... not from a scientific burst pressure standpoint, but if it's a .38 +P, and you're shooting 158gr .38 +P's, you're probably close to the max rated pressure.) I would love to learn more about rated pressures / pressures generated by a particular load / powder, etc.... if anyone would like to educate me
