What's "true" or "false" here? Nothing. It's all a matter of opinion and personal preference.
As an owner of nine Glocks over an 18 year period, in all calibers except 357Sig and 45GAP, including two each G30s and G36s, I LOVE my G36s.
I no longer use ANY other Glocks for CCW.
I practice with the G36s weekly, always 50-200 full power premium rounds.
I don't notice recoil at all with the G36, that is, it simply doesn't get my attention.
I strongly disagree that the G36 recoil resembles G27 (or other .40S&W pistol) recoil. G36 recoil, like that of any .45ACP pistol you can name, is a rolling sort of push, whereas .40S&W recoil is more of a "spank" or a snap. Sure, felt recoil with the G36 is more than the heavier, wider-backstrapped G30, but the point is that it's trivial, painless and not detrimental to making accurate followup shots.
As for "the pinch" between the magazine floorplate and the base of the gripframe, it's a recognized problem with ALL the mini or smaller Glocks, at least for many folks. I've personally had it with the G27 and G36, and solved it in both cases by substituting the appropriate Pearce Grip floorplates (their "Plus Zero" and "Plus One" types both work well), which change the angle of the floorplate extension to the gripframe so as to make pinching less likely, and also fill the gap that occurs with the stock mags at the front of the floorplate extension.
There are a lot of vehemently negative opinions expressed about the G36 here and at Glock Talk, which I find odd. In many cases, these seem to come from novice or inexperienced shooters, but not in all. Gun choice and preference is obviously idiosyncratic.
Many of us who actually own and shoot these little guns think very highly of them, and have NO problems with accuracy, precision, reliability, ease of shooting, capacity or carry. I agree with recommendations to try before you buy, obviously, which is good advice with any model of gun which you'd anticipate purchasing, insofar as possible. Best.
