Yeah I've been aware of companies like Bowie tac etc for quite some time. I'n fact a longstanding glock gripe has been the grip angle and the finger grooves. I've considered doing the "fill the blackstrap with putty mod " and grind the blackstrap for a more neutral wrist angle such as that on the 1911 but it's a helluva mod to undertake. There is a beaver tail attachment that claims to change the grip angle as mentioned in the video you posted. I'd like to try that out. Don't get me wrong I'm not bothered by the stock angle but a more natural point of aim would be nice.
I wonder if the polymer  material will take to front strap checkering like the 1911 once the fringer grooves are grinded down.

I know Bowie and he does do very good work.  The other guy that does excellent work is a guy named Lane at coldborecustoms.  We have bounced ideas around and I do a couple things that no one else seems to be doing yet like the magwell and reshaping the stock Gen4 mag release button.  Give it time though.

nice work, surf
you should start a business modifying and building guns
i think you would do well

Thanks, I appreciate the comment.  I do a great deal of armoring and smithing work as a part of my profession.  I adjunct for a Major weapon manufacturer and can teach an armoring course for them, but don't have the time.  I do some work word of mouth for people I know but I don't openly advertise because I still have a full time job and the extra workload can put me way behind in projects.  Same problem with many of the guys doing this professionally and turn around time can be 2-3 weeks or longer when you send it to the mainland, so I feel for the local guys.  I get a lot of inquiry from the mainland about a lot of things, but for custom firearms work I decline if it requires an FFL as I am not allowed to hold an FFL at this time due to a conflict of interest.  Thanks again for the comment. 

Yet you void your warranty with Glock when you stipple or do a grip reduction job.

Yes this is correct.  Any custom work outside of the manufacturers recommendations will usually void the warranty on any firearm.  At least with the Glock, if you wanted to do so, you could return it to stock configuration including getting a new factory frame with the serial number plates swapped without too much difficulty other than perhaps having a wait period and paying for it.  Certain manufacturers may require the factory or certified armorers for that company to perform the work.  But the beauty of the Glock as an example is that they are cheap enough to begin with, so for many alteration becomes an easier choice.  I will also note that when you send your Glock into the factory for a service issue, they gut the entire pistol put in all new components, even if it wasn't the issue specified, they then test the entire pistol including dry function and live fire function and return it. 

I will also note that I learned quite a bit about custom Glock work from a highly regarded person in LE and in the shooting world in general.  He happens to teach the Glock armorer, advanced armorer and Glock shooting instructor courses.  He will reinforce correct protocols for factory specifications of the weapon when teaching officially, but he also competes and is more than willing to share techniques to his advanced students after hours.   

I owned 1 Glock since around the 1994 time frame and didn't own any others until about 3-4 years ago.  As a long time 1911 guy I really hated it and it took a long time before I accepted the pistol but I couldn't ignore the fact that it dominated in certain categories and was huge in the shooting world in general.  Besides the feel of polymer vs steel the thing I hated the grip angle.  However I stuck with shooting the pistol and noted that my times given speed and accuracy were amazing.  The amount of control I had over the pistol with the minimal amount of recoil was puzzling at first.  Reviewing video I noted that my support wrist being canted at a greater angle was more aggressively locked out and that provided more control.  It definitely took a bit of re-learning a new natural point of aim, but the results I saw on timed drills was clear.  Now IMO the angle is what really benefits the Glock pistol when a good aggressive thumbs forward technique is used. 

On the other hand the Grip Force adapter does indeed help with reducing the angle bringing more into what most Americans are used to.  Grip reductions on the backstrap also provide this same effect.  I do not generally advise people to do their own DIY fill and sand jobs as those are the ones that fail the most.  Improper prep, technique and use of correct filler often causes it to break loose over time.  This is also were you can get into frame integrity issues discussed above.  In general I prefer to use a heat and roll method to reduce the hump on the backstrap.  Keeps the pistol frame solid.

A couple of my personal pistols.  Texture design is a matter of taste and texture can go from mild to aggressive.
Gen4 G17



Gen4 G19 set up in a carry configuration so only the front strap is textured after finger groove removal. 

Awesome stipple pattern. How did you achieve that?

Was bored so I decided to try my hand at stippling... Nothing beats the stippling for texture and a good grip....

Awesome stipple pattern. How did you achieve that?

Experimenting with different designs.  Technique is trial and error.  I do a few different patterns, such as the standard golf ball dimple, reed pattern, rice pattern, tree bark pattern and a crackle type pattern.  Some patterns lend to more or less aggressive textures.  My favorite designs are the reed and tree bark designs, my least favorite tends to be the golf ball dimple.  But like most things, preference varies from person to person.
