Modified A&G Grip Extension PM9

[Ol'coot]

Tilos,
I have sent you a PM about my hobby machines

[jreXD9]

I got one of those and the gap isn't nearly as bad as what's in your picture. It looks 100% better now.

I'd take one of each; 6, 7, and 8. I just picked up a pierce extension today and it helps with the 6 rounder, not with the look though.

As explained in my original post, that pic is with the mag pulled out as far as it could go. Other pics show more.

This just makes me so mad! Kahr buyers pay a premium for a beautiful and well crafted piece of equipment. Then to stick us with something like this???? I cannot believe there isn't a better product on the market. As many others have said, I would definitely buy a few.

Posts upstream show it corrected. Might be an opportunity to figure out how to do it and sell ready-to-install perfect spacers on the forum. If the market exists, expand into selling 6,7 and 8 round complete perfect mags. Hey there's your product name right there. Not every day I give away a good idea.

I can't even break down and clean my gun without f'ing up. I've got no chance to machine something like that...to a level of quality I would want. It just amazes me that nobody else does it. And is the A&G really that bad? I can't imagine they would even sell something with a gap like that...Looks like it came out of a happy meal.

Amazing work Ol'coot! All of us Kahr owners are dealing with the same issue with stainless steel showing on the mags, both with and without the extensions. You certainly have a talent. I did a similar thing (home do it yourselfer) with Agrip material on the PM40 6 round mag with extension AND the 5 round mag which does not have an extension and SHOULD fit flush or at least match the pistol grip. Your work is far more professional, but outside of my scope. I simply do not like the appearance of the stainless, but it may not bother everyone in the same way as it does me. You can see the Agrip solution on my separate thread named something to do with Agrip. Again, beautiful job. Please send your photos to Kahr.

Garyb,

Thanks for the very kind words and encouragement, I want to move forward on making a run of prototype parts to see just what kind of market really exist for this item. I have very positive feed back from everyone that has seen it. My biggest issue now is finding the time to complete the 3D model as I am very busy at work and just have a hard time getting back behind the CAD system at home. I hope to make some prototypes for the 6, 7 and 8 round mags.

I am certain there will be a market for what you have done with your model of Kahr. However, there are so many models with the same issue, that it may require variations in fitting. Likewise, there may be liability issues to consider/research. Please understand that I am not trying to discourage you nor insult you in any way, but the reality is that mass production for business is different from felf gratifying hobby work. (I got myself into taxidermy years ago, because it was something I always wanted to do since a little boy. I thought it might make a good part time income. Now my custom detail taxidermy work is at par or maybe even a little better than the production work of some of the local taxidermy businesses. I already have a wonderful full time job with a very good income and am very close to retirement at which time, the taxidermy might be more welcome. For now, the taxidermy Hobby became WORK. I decided to back off and now I only do a max of 6 shoulder mounts and focus on limited subjects (deer or bear) each winter. I don't want to be tied down in a shop all year. I have a life and want to be completed with the winter taxidermy jobs before spring turkey season kicks in. Likewise, taking inquiry calls and taking in animals during the hunting season (which is my passion and healing time) is a pain in the .....). So the message is that, what was once a fun and fulfilling hobby and life long goal, has now turned into aggravating work. You probably don't need to be warned to be careful with your project - as your work is great and there is a good opportunity for business. Perhaps Kahr will pick up on it if approached? Best of luck.

Thanks for the insight and advise as open constructive comments are always appreciated. The design and construction of precision tooling for manufacture of tight tolerance plastic parts from engineering resins is my profession of 38 years and l agree with all your comments. I have found it is better to approach this type of thing slowly and consider all of the risk before jumping in head first. I am also only a few years from retirement and looking for things that I can do and still stay in my area of expertise to occupy my time and maybe supplement my income a little. I spent some time on CAD system last night and have the design for the 6 round magazine 95% complete. My next step will to be make a few prototype parts using the (SLS) Selective laser sintering process . This highly accurate process will give me a few prototype parts that can be thoroughly tested without the high cost of making a injection mold. As with anything there are cost, time and risk involved and each must be weight out against the final benefit to determine if the endeavor is actually worth perusing. I will keep everyone update on my progress and may even ask for some people to to take one of the prototype parts and test it to get real world feed back before moving forward with any molds.

Good for you! Sounds like you enjoy your field of expertise and obviously you are great at it. I am guessing that you are on to something. It will benefit Kahr owners for sure. Best of luck.

[Suprman]

if you make some for the 5 and 6 round pm40 mags, i would be very interested. hate that gap with a passion and my friend got his finger caught by the gap in the 6rd mag when firing the gun.

[REPR3D]

Wow, that's clean! Kahr NEED's to take some design notes. I agree with the premium we pay for these that there is a lot of improvement to be made in the mag fit dept. If you decide to sell these, i'm in line! Great job!

Ol'coot, that is some BEAUTIFUL work! I'm so envious of your skills and expertise!

My father was a model maker, primarily in the aerospace iindustry, so you know the skills he had as he did it all the old-fashioned way with no CNC stuff! If I had his knowledge and expertise, I'd be running my own custom gun shop!!!

I would pay top dollar for this work as my PM9, CW9 and CW40 actually cause me considerable pain on occasion during extended shooting. I don't have big hands or fat fingers and my pinky finger gets the CRAP pinched out of it during extended shooting.

Not only would I love to be a "test dummy" for your work, but I would be happy to pay for the previlage!!!!! I have a Pierce extension on my P380 (not an issue) and my PM9 but not on my CW9 or CW40. The P380 isn't an issue as my pinky finger lays right in the center of the extension-and it doesn't shoot hard anyway. Even without the extension, the CW9 and CW40 both "bite" my finger.
