Over the years those of us who favor the 1911-type semi-automatic pistol have been accused of being mesmerized by the pistol. At the same time we stress that the 1911 is not for everyone. The Glock is much the same, not for everyone, and a pistol that does not suffer poor handling. Those who go through life asleep need not apply for either handgun.
On Mar. 1 2006 armed felons robbed the Chemung Canal Trust Company in Big Flats, NY. Those involved were Anthony Horton, 33, and Brian Adams, 45. These robbers fled the bank in a vehicle along with the sum of $1,900. Approximately an hour after the robbery Trooper Andrew Sperr stopped their vehicle for what appeared to be a minor traffic violation. The felons engaged Sperr in a gun battle. Sperr was struck and killed by gunfire. However, he had been able to hit each of the robbers, wounding one four times.
The .45 GAP is similar to the .45 ACP but uses a shorter case. This short case allows the cartridge to be chambered in compact handguns of basically 9mm size. While the slide is heavier, the Glock Model 37 .45 GAP is barely larger than the Glock 17 pistol in 9mm. This is possible due to the special short case and the low pressure of the .45 GAP cartri dge. Like the .45 ACP, the .45 GAP works at modest pressure. The .45 ACP operates at about 21,000 psi while the .40 and the 9mm may operate at well over 30,000 psi. The .45 GAP is rated at 23,000 psi or about the same pounds-per-square inch pressure as a .45 ACP +P loading. The .45 GAP uses a special extractor groove considerably different from that of the .45 ACP and also a small pistol primer rather than the large primer used in the .45 ACP. The .45 GAP is similar to the .45 ACP but the cartridge is also unique. | M21 | M37 | |

The slide of the Model 37 is the same thickness as the Model 21 at 1.13 inches versus the width of 1.01 inch for the Glock Model 22 .40, meaning that at present Glock 21 holsters must be used for the Glock 37. I am certain major makers will pony up and produce proper holsters.
The difference in feel of the pistols is very noticeable, with the Model 37 presenting a better balance than the Model 21. Let me make this point: if you have large hands and can handle the Model 21 the Model 37 offers no advantage. The .45 ACP is available in more diverse loadings and offers more power than the .45 GAP in the +P loadings. The .45 ACP is more efficient with bullet weights over 200 grains including the standard 230-grain loadings. But a person with large hands will probably control the Model 37 even better and those with smaller hands simply cannot stretch their digits to accommodate the girth of the Model 21 Glock. The low pressure .45 caliber cartridges solves the problem of wound potential and weapons wear. You will still have to shoot straight but the wound potential of the .45 GAP, with its wider frontal diameter, is obvious.
Excellent Handgun
Overall I find the NYSP service pistol an excellent handgun. The NYSP responded to a real failure with an intelligent choice. The Model 37 is a result of thinking outside of the box. While the pistol is based upon the proven Glock design, the Model 37 incorporates changes that make it suitable for a special short case .45 caliber cartridge. Modern powder and brass technology made the cartridge possible. The Model 37 may prove to be a serious contender in the future. While the .40 and .45 caliber pistols will remain popular, the .45 GAP is an option that cannot be ignored.
Also, the ammunition companies have really raised the bar on ammunition and produced a number of loads that have excellent potential. Winchester has introduced a 230-grain SXT loading. There are some who felt that the 230-grain bullet weight would not be successful in the .45 GAP. Winchester has proven them wrong with the proven SXT bullet at 850 fps. This is squarely in .45 ACP standard pressure territory. Winchester also produces a very good practice loading, the Winchester USA white box 230-grain loading. I have made extensive use of this load with good results.
I have also made use of Cor-Bon’s entry. Civilians like high velocity and probably do not need the same level of penetration as peace officers. The Cor-Bon load I like the best is the DPX, a 160-grain all brass hollow point at a solid 1,070 fps. This is a good personal defense load that seems to exhibit a good balance of expansion and penetration. Another choice is Cor-Bon’s 230-grain ball loading. The Performance Match line has proven very accurate in every pistol I have tested in 9mm and .45 caliber and the new .45 GAP loading is no exception. This is a good choice for pistol matches and informal targets.
Since the pistol is polymer I went Kydex with one holster. The Bear Claw paddle has given excellent results, with good retention and real speed. This is a holster with many good features. While the paddle was first designed for peace officers, the paddle has much appeal to many citizens as the pistol may be taken off quickly and stored with the holster without much difficulty in placing the holster back on.
Another good choice is the Blocker cross draw. I have been a fan of Blocker holsters for almost 20 years. The Blocker cross draw is a quality leather holster with good features. The stitching is excellent and the holster mouth is reinforced for retention and security. The belt loop is in the proper position for a crossdraw and this comment comes only from much experience. When seated or when driving a vehicle, there is no draw handier or more comfortable than the cross draw holster.

| As you can see the .45 GAP and the .45 ACP are comparable. Only with heavier bullets is the .45 ACP superior. The wound ballistics offered by the .45 GAP are certainly acceptable. As for accuracy, the pistol offers comparable accuracy to the Glock Model 21, which is widely regarded as the most accurate Glock pistol. | |||
