Prototype Mag Extensions- 8 types now ? Which lenth best?

[bamboobob]

Hi: All

Have wanted straight extensions for a long time. 
I started on this project on Saturday after Labor day

Prototypes
#1          1/2" +-      steep ramp ,   blunt,    flat tip                    5.1 gram     smooth   
#2          3/4" -        45 deg            blunt.    flat tip                    9.2              smooth  (thicker in back)
#3          3/4" +-      45 deg            blunt,    pointy flat tip         7.4              smooth with cool lines
                                                                                                         with slight rounding, sides of tip
#4          3/4" +-      steep 60 +-    blunt,    pointy flat tip          5.3              smooth
#5            same                                                                         6.4             smooth  (thicker in back)
                                                                                                                        with very cool lines
#6            same                                                                         6.6             "stepped coin" very nice
#7          3/4  x  3/4  x1 3/4   raw block                                     30.2
                                             (with slots and holes for mag  )         

#8           same,  but free cut     steep and curving                   10.3
                                    (will be shaped down, with bump in middle of  front)

Pointy means side view and smaller flat tip
     
What would be better 1/2 or 3/4?   both?
What about big hole/ hollow  to lighten?
I hope to drill some out and free sculpt some.

                  All advice would be greatly appreciated.

Thanks, Bob

I feel hand size will dictate what works best for each individual.

Personally, The plastic Pearce grip extenders for the PM9 and Colt Pocket 9 fit the R9 and worked great for me.  The gradual curve makes them fit a wide variety of hand sizes in my opinion.  I just did not like plastic with a heel mag latch.  Their shape was much better for me than yankee's design.  JMO

MRC  Thanks for your reply
I agree hand size matters (oops lol), maybe more so on hooked ones when tip, ends up at middle of little finger.  An old AMT 380 back-up had a nice one, hooked with radius and thin tip (matched two fingers on grip exact-no little finger)

CNC guy just came by with another sample, very nice 3/4", steep ramp with lines.  Next few may be steep ramp 3/4" smooth and/or cool lines(asymmetrical curved and straight lines).  Then 1/2" smooth, blocks and possibly stepped coin.  All of this is mega huge pain in butt for us even minor stuff.  Basically all are custom, lots of hand switching and hand work.  Looks like may finally get a little bit better.  Hours of computer coding for him maybe 20 pages. Typing is huge ordeal for me.

Two main questions for preference           1/2"   or  3/4"   ?
                                                                  smooth or other   ?

Hope to eventually get around to pictures.

Thanks again.

Sorry Bob, I am a totally Visual, Kinesthetic kind of guy.  I have to either see a pic a or hold one to form a valid opinion. 

It's not that I don't care buddy.  I appreciate what you're doing.

Thanks

Bob,

 This is great news! I too am on the visual side so some pics would be great. I do have a big hand (size 11 gloves) so I am guessing the 3/4 inch might be best for me. I also like the idea of the slight curve.

 I have two of John's straight extensions, but I would like to get my hands on six more.

 Good Luck, keep us posted.

Very interested as well.  Look forward to some pictures.

Thanks for all the positive response, it is very encouraging.
I just tried loading disk for old 1.3 argus camera, it started to take,  after many "next" 's  computer warned me not to so I said not to twice, then I think it may have finished any way.
Might try more testing or try email picture from cell phone.

[bamboobob]

testing picture upload   (I think I found "downloads")

now picture in docs   might work   might not   might be attachment ?

well here it goes

             WOO HOO it worked !       (click on pic for more detail),
                                                  curvy lines are straighter and closer on other side

       This is  "steep ramp" -  3/4"

[Robar233]

Bob,

 I get the idea of less weight. My only concern with this
"skeleton" design would be how it feels during a reload?
 I have to out 60 rounds through the pup in one sitting.
 This design could be a little painful on the palm of the hand
 doing the reloading.

 Just my 2 cents.

Good point, I'll try with that in mind.
What about push on flat with thumb or finger?

Will try another picture of more rough unfinished prototypes.

I just tried (inserting mag)  many times, just fine with palm, very nice with thumb or finger(seemed very natural).
Tried with both empty and full mag, very little pressure needed.
The part does have a flat bottom.

Thanks again for help and interest.

[Reinz]

Just going on looks and not being able to coonfinger it; I like the middle one at the bottom.  It's justs more "finished".

But I do like the idea of a snubbie, like the one on the far right.  Just wonder how it works out?

[Ballistic]

Bob, thanks for taking on this project.  Please count me in for some once they are complete.

[Reinz]

Howdy Ballistic, welcome to the forum.

[bamboobob]

Welcome Ballistic, thank you so much for your interest.

Reinz: Thanks for response, pic of more finished "snubbie" still has not made it to e-mail.
                                                                                                          (now here)
A pic with "stepped coin" in it finally showed up in e-mail (these are rough pictures of rough prototypes).
