Most recently, I rented a CZ 75C with a decocker - it was either a P01 or a PCR. I was just ok/average in DA but right on target in SA.
I have a competition pistol on the way that is DA/SA and now I’m thinking that I need more of these heavier pistols
As TunnelRat noted, the CZ you shot had an alloy frame. There is also a steel-framed version of that size CZ too, called the CZ-75B Compact (capital "C"). That model has a frame mounted safety rather than a decocker, and can be carried and started from cocked & locked -- or from hammer down, which gives a longer and heavier first trigger pull, but lighter shorter pulls for all following shots.
The CZ you shot had a decocker, and the DA first shot from that gun starts from (and decocks to) the half-cock notch, which gives you a slightly lighter and shorter DA trigger pull than the steel framed model offers, but the rest of the trigger pulls are like the steel-framed model -- shorter and lighter than the first trigger pull. (The steel-framed version can also carried and started
safely with the hammer on the half-cock notch just like the alloy-framed models. Like most newer gun designs, these CZs have a firing pin block mechanism which won't let the firing pin or striker move forward unless the trigger is pulled fully to the rear. That makes them drop-safe, too.
A gun's weight with Browning Short Recoil Locked Breech (BSRLB) guns -- which is the vast majority of semi-autos shooting 9mm or higher calibers -- can affect recoil but has almost no effect on accuracy.
That's because the bullet leaves the barrel before the barrel/slide has moved more than 1/10th of an inch to the rear. With such a small amount of slide/barrel travel, only only a small amount of recoil can be transferred to the frame for the first or following shots. Once the bullet is gone, the rest of the recoil is transferred to the frame. So there's almost no barrel rise until after the bullet is gone. (That shouldn't affect accuracy, in any event, as it would theoretically rise the same amount with each shot.) That means a heavier or lighter gun doesn't recoil much differently until AFTER the bullet is gone. (With revolvers or fixed barrel guns, the weight of the frame does affect things, as the barrel starts to rise as soon as the bullet begins to move down the barrel.)
That said, a heavier frame will move less in recoil than a lighter framed version of the same gun, so the shooter can often get the gun back on target just a a little bit quicker. It may be more pleasant to shoot, too.
If you're shooting heavier hammer-fired guns better than lighter striker-fired guns, its likely NOT due to the heavier weight or the DA/SA triggers of those guns, but to other things about those guns that help them tbe more accurate in your hands -- how well the gun fits your hand(s), whether they have better sights, better trigger, sor better slide/frame lockup.
One of the advantages of most striker-fired guns is that the first and following shots all have the same trigger pull, while any hammer-fired gun that isn't single-action only, has a different first trigger pull (which is DA) and the following SA shots.
Keep trying different guns, and you may find something that your really like, but don't believe that weight or action type (striker vs hammer) along are what causes some guns to do better in your hands.
