The mailman was good to me today. I got home the mailbox was full of some small parts. So Kaden has been sick and was sleeping on the couch so I got to go to my "man cave" to play.
I got:
The 3.5 trigger set up...this was actually from a LGS....but he mailed it so I would not have to drive over to get it
extened slide lock release
locking block
pins/springs
grip plug

continued in next post....

Here is the slide lock. I had a factory one for reference but I change this to the Lone Wolf extended.


Longer and easier for my fat fingers to use.

OK so here is the frame all put together. I didn't show every part like springs and the back trigger assembly because well I don't want to over due it with pictures.

The frame is good, I am pleased with it. This part of the build is right at the $235 with the frame, parts, shipping and FFL transfer.

So far so smooth...


Today I did get the word that the slide has in fact shipped so that will be the next part coming. Nothing else on order right now waiting for the slide to get here and go from there.

OH for fyi I chose to get the .40 cal set up initially because I then can purchase the 9mm and 357 sig down the road and shoot all three in this one gun. So now this actually a Glock 24. The .40 cal version of the long slide. Same as the 17L just not in 9mm.

I understand what you are saying though.



Yeah I was hoping my logic is solid on this

So, you should build the 40 and then get a conversion barrel to 9mm.
The 40 is thicker than the 9mm and you will need it for the slide.
If you already purchased the 17L slide (9mm), you might have a problem getting a 40 S7W barrel to fit.

As far as building an M&P, To my knowledge, finding a lower and upper for M&P's is a BIG TASK!

Have just finished taking a 9mm CORE and milling the slide with three windows on the top and sides to reduce weight.
Added a complete APEX trigger job with Straight trigger and competition springs.
The slide just went out to be Cerakote finished. I will have it back on Monday and photos to follow.
I have a C-more STS on top with tall S&W sights.
Added a maxwell to aid in speed reloads and away we go.

Looking good !!!

Thanks caleb!


Sorry let me clear it up i have ordered the 24 slide its in 40. So i CAN buy conversions to 9mm and 357 sig. I hope this makes more sense.

Here you go


LWD 9mm conversion barrels will allow you to shoot 9mm ammunition from your Glock 40 S&W or 357 Sig handgun. These conversion barrels are easy to use and install the same as any other barrel, simply drop it in, no gunsmithing or other modifications are required. We do recommend you use the correct 9mm magazine with these conversion barrels to guarantee reliable feeding.


About 1% of our 9mm conversion barrels are affected by the poor performance of low powered 115 grain ammunition causing a Failure To Eject (FTE). A good example of ammunition that is “most likely to fail” is Winchester White Box (WWB). This rare failure is too low a percentage to make an issue, however it is one we are well aware of. The fix to resolve this issue is quite simple:

1 Clean and lube your slide and barrel.
2 Shoot 1 mag to 1 box of good quality +P or +P+ ammunition through the barrel.
3 Try the FTF ammunition again. If it runs... great! If you experience more failures you will have a couple choices to make:
Fix A Reduce the recoil spring weight to 11 lbs. Cost is about $25 for stainless steel guide rod and reduced power spring. See guiderods here.
Fix B Shoot 124 gr or a better quality 115 gr ammunition exclusively. The FTF 115 gr ammunition you are currently using is no longer a valid option.

What causes this problem? Several issues come into play.
1 The 40 slide and (40 conversion) barrel are thicker than standard 9mm slides and barrels. This extra thickness equates to more weight. The combined extra weight taps the energy of the "weak 115 gr ammunition” to its complete demise. It simply lacks in power and fails to reliably eject the spent round.
2 Every once in awhile a Failure To Feed/Failure To Eject (FTF/FTE) is caused by a fit issue. We resolve fit issues by pumping +P or +P+ ammunition through the gun. This hot ammunition provides extra pressure and the pressure will positively align any and all components. Once they are all aligned there is no longer a fit issue. The FTF/FTE is usually resolved.

FYI: Several manufactures are currently producing low powered 115 gr 9mm loads. This ammunition is also known to produce failures in all standard model Glock 9mm pistols.


Please note: To convert any .40 caliber gun to .357 or vise versa you don't need a "conversion", just purchase the barrel to the corresponding Glock model.

Don't forget to buy the proper magazines for your conversions.

For converting your Model 27, 33, 23, 32, 22, and 31 to 9mm :
9mm Model 27,33 9mm Model 23,32 9mm Model 22,31
Glock OEM Glock OEM Glock OEM

Yep.....a $100 barrel and a mag or two and I will be able to shoot 9mm do it twice and I can shoot 357 sig.

BUT I have to finish the first one...
