Specs on the Gun which was detail stripped and cleaned thoroughly before the start of the test as well as being well oiled using Prolix Xtra T Dry lube formula.
S&W SD40 VE Aprox 1100 rounds through it before test begun
Apex SD Carry/Duty spring kit fresh springs installed for test
Apex Action Enhancement Trigger
Ameriglo Tritium Night sights.
2 SD factory magazines
1 Sigma factory magazine
1 Sigma factory magazine with apex +3 extension
1 15 round SW40F magazine
I begun my 2000 round test by firing 384 rounds today.
200 Winchester White box 165 grain
150 Blazer brass 165 grain
34 Remington golden sabre 180 grain
I wish I could say it went flawless but alas I cannot, I experienced 10 stoppages today.
The list of Stoppages is below. No malfunctions to report as of yet.
On the 16th shot I had premature slide lock (PSL) with a factory SD magazine.
124th shot PSL Sigma magazine
161st shot PSL SD magazine
280th shot had a nose down FTFeed Sigma magazine with Apex Extension
333th shot FTFeed nose up Sigma mag Apex extension
(Note: the following Stoppages wre experianced with Remington golden sabre 180 grain JHP)
357 FTFeed nose down Sigma mag Apex extension
360 FTFeed nose up Sigma mag Apex extension
363 nose up Sigma mag Apex extension
382 PSL SD factory mag
383 PSL SD mag
Here are some pics of the stoppages
At some point today I also lost the white ring around the tritium in the front sight.
And one showing how dirty the muzzle got
The gun will not be cleaned until I reach 2000 rounds. I will not oil again unless I encounter more frequent stoppages.
So far we have 10 stoppages out of 384 rounds. That is way more than I expected. I also need to replace the front sight.
I need to do more testing on the apex mag extension however I found it odd that the only failures to feed I had that could be attributed to the magazine was with the mag extension.
All other stoppages were PSL which may be due to a weak slide lock spring., the first one may have been my grip but all the others were after I made sure my thumb was not anywhere near the slide lock.
384 rounds fired 10 stoppages
Overall failure rate of 2.6%
97.4% reliable
I will update this thread ofter each range session.
