GLOCK GEN 5. DIFFERENCES FROM PREVIOUS GENS. (38 AND COUNTING...)

GLOCK GEN 5 (17, 19, 34 & 26)  CHANGES W.R.T. GEN 4, AND MANY TIMES GENs 3, 2, & 1 AS WELL.  (MOST, BUT NOT ALL APPLY TO THE 19X, AS WELL)    This is a work in progress (obviously...).  

Much has been made of the main 5 changes (1 through 6 below, less #2), but there has been much less discussion of the others.  "Over 20 changes" was a quote I heard a lot just prior to the release of the Gen 5 guns.   So for, I have found at least 38 differences form Gen 4 to Gen 5.

My take :: This is a much more distinct set of changes than 1 to 2, 2 to 3, or 3 to 4.   The result is less parts commonality.  (This is a GOOD thing, as the new designs are better.)

This is a fairly complete list, but if I have omitted anything, let me know in the comments.    Thx.

1.     ADDED A MOLDED-IN MAG WELL (BUT NOT ON THE 26-5 AS IT WOULD INTERFERE WITH GRIPPING THE GUN)

9.    FIRING PIN SAFETY PLUNGER GEOMETRY IS NOW LIKE 42 & 43; THUS MAKING THE ENGAGEMENT WITH THE TRIGGER BAR A BETTER ANGLE, AND MORE CONSISTENT

10. TRIGGER SPRING IS A COMPRESSION SPRING, (NOT TENSION)

11.  SLIDE LOCK SPRING IS COMPRESSION, (LIKE 42, 43)

12. AMBI SLIDE STOP LEVER SPRING IS COMPRESSION TYPE (AND USES THE IDENTICAL PART (G# 39567) AS TRIGGER SPRING AND SLIDE LOCK SPRING)

17. TRIGGER GEOMETRY & SPRINGING == BETTER TRIGGER PULL & BREAK

18. LOCKING BLOCK GEOMETRY

19. NOTCH IN FRONT-STRAP FOR MAG REMOVAL (ALA GEN 1)

20.MAGAZINE FLOOR PLATE GEOMETRY (ADDED FRONT FINGER HOOK)

35.LOCKING BLOCK PIN GROOVES ARE SHALLOWER AND WIDER (VS G1-4)

36.TRIGGER W/TRIGGER BAR GEOMETRY ALTERED TO ALLOW FOR THE AMBI SLIDE STOP LEVER; AND TO ACCOUNT FOR THE COMPRESSION TYPE TRIGGER SPRING

37.EJECTOR TAB IS WIDER, STRONGER, AND IS CANTED TO SLIGHTLY FOR BETTER CONTACT WITH THE CASE

QUESTIONS ::

1.     CAN A GEN 5 FIRING PIN SAFETY PLUNGER BE RETRO-FITTED INTO GEN 4 OR GEN 3,2,1… GUNS FOR PREVENTION OF TRIGGER BAR FLEXION PROBLEMS?   AND/OR SMOOTHER TRIGGER PULL?

NO.

2.    CAN A GEN 4 SLIDE STOP BE FITTED INTO A GEN 5?

LIKELY NOT.   (THE RAILS ARE THICKER IN GEN 5).

3.    DOES A GEN 4 CONNECTOR WORK IN A GEN 5?

YES.
