Yes - if you buy a good brand - which is what my first reply asked the OP. We determined that he was probably referring to the K-Warrior Maruzen/TM clones, which have metal slides and many tolerances which are way slacker than they should be because the 1911's shape does not allow accurate moulding without using expensive sliding mould technology, because the real thing's parts are milled when produced in metal. The simpler shape and plastic materials of the Glock makes that less of...

...an issue, as it does with the real thing

The parts that matter though are simple shapes, as simple as each other practically. The materials is a minor issue, making the runners for a slide is simple right angles on the frame, plastic or metal its not a big challenge. Slides are both metal so again same thing.

You're making out like making a 1911 is a huge design problem because its old but in Airsoft the designs are practically the same for the slide internals which is where it matters. The externals are more conplex on th...
