Glock Grip

I was sent this email from an avid Glock shooter:

 

“Just FYI    For some time I was shooting a thousand rounds a month in Glock model 19s.  At some point perhaps two years ago, shooting became painful, the gun would give me a ‘blood blister’ on the end of my lesser finger.  Very bad on my preferred right hand, some but not as much on my left.  The guns I usually practiced with were two ‘Generation 2’ Glocks which had a cut-out at the front bottom of the grip, supposedly to assist in gripping the magazine for removal.  My finger was rubbing against the edge of the cut-out.  Obviously I had changed my grip.  I’d had a slight slack period in my shooting but had still been gun handling, apparently it had happened then. Because of this, my shooting was not as consistent as previously.
I made of point of positioning my hand so that the tip of the abused finger wrapped further around the grip avoiding that little area of concern.  Held thus, my shooting seemed to improve, a little, but looking back, that may have been only because I was shooting more regularly again.  On every shooting session however, I still had some degree of irritation, pain, or blistering, depending upon how much I remembered, or not, to ‘properly’ hold my gun as I had previously.
During todays shooting session, at one point I noticed rather disgustedly, that my finger had bled on the gun.  I taped my finger and continued my practice.  Today also, I was noticing how the last several generations of Glock magazines for the model 19 seemed to be longer that the first ones.  I had used first generation magazines for a very long time.  These were the ‘squeeze to remove’ baseplate rather than the later ones with the spring loaded button.
Later, at home, I compared an old retired magazine to 3 variations of the newer magazines.  Gripping the unloaded gun, I felt pain in my poor damaged finger while one of the newer magazines was in the gun but not while the older one was in place.  My aging but still curious mind soon discovered that with the newer, longer magazines, all grip pressure from that finger was on the cut-out, but because the older magazine was fractionally shorter, my finger rested on the cut-out and the front of the magazine baseplate which took the pressure from my grip so I was not getting cut from the cut-out..
Two years of frustration, poorer shooting and pain to my finger because Glock changed the length of its magazines.
Note that starting with the Generation 3 Glocks the cut-out is no longer present.  But Glock added finger ‘bumps’ to the grip to lock in the position of the shooters fingers.  These jam my longest finger into the trigger guard and it hurts.  So, like many other Glock shooters, I have had to grind the new ‘improvements’ off of my Generation 3 guns.
Authors note:  Some readers may comment and ask why didn’t I notice that the Generation 3 guns didn’t hurt my finger?  Well, 1.  I rarely shoot them, doing almost all my practice with the older guns and 2.  I may have simply thought that I had a better grip those days shooting them.”
Comment:  Glock “perfection” has changed greatly over the years.  Know that mixing new and old parts may cause issues.  Some of the Gen 4 pistols have different recoil springs cuts then other Gen 4s of the same model.  Extractors, locking blocks, and a great number of small parts have changed over the years.  Magazines have changed from non-drop free to full metal lined mags that drop free when the mag catch is depressed.  Like this shooter found, changing parts in your pistols may have unexpected results.
