As a first gun it's not a great idea to aspire to a particularly modified one.

Heavily upgraded GBBs are typically comprised of parts from several manufacturers each with their own interpretation of how to make your GBB work. Because none of these aftermarket parts manufacturers will be actively cooperating with each other (or more importantly the manufacturer of your base model) you may end up with a powerful, but not very reliable GBB. Many frankenguns also end up less accurate than their stock counterparts. Until aftermarket parts manufacturers actually sit down and learn how to play together, they will not make parts that fit as well as the stock parts which were all designed in the same house.

Nothing frustrates a gun doc more than a frankengun not of his own creation. Your doc ends up blowing a lot of time figuring out how single or compound failures are occuring.

At the risk of more typical power, choose reliability for your first GBB. Learn it's quirks and mode of operation then gradually upgrade it yourself. Besides, most pistols with minimal upgrades and propane are quite powerful enough for game play.

Try to pick a common GBB as a first as you will have access to repair help from more owners and a larger base of experience for them to help you from. Much better access to spare parts too.

The Para Ord comes with a metal particle filled slide. The particles add density for a heavy aesthetic. Metal particles do not add strength. They actually degrade crack toughness. I note that lightweight WA slides typically outlive HW slides.

It appears to me that the TM Hicapa is propane ready despite it's plastic slide. Has anyone broken a slide yet? It's also shown to be one of the most reliable builds out there.
