One 1 oz, 6.1 g protein.
Every 100 kcal of pastrami brings 14.8 g of protein. On that measure it ranks 49th of the 133 meats in this database and 143rd of all 796 foods on the site. Measured by weight instead, its 21.8 g per 100 g ranks 102nd in its group.
About 59% of the calories in pastrami come from protein, which makes it very protein-dense - close to the practical ceiling for a whole food. Foods in this band are the ones that let you raise your protein intake without raising your calorie intake much at all.
Weight for weight, pastrami has 3.7 g of protein for each gram of fat (21.8 g against 5.82 g per 100 g).
Set against beef hot dog, another meat entry in the database, a serving carries about 0.5 g more protein (beef hot dog has 5.6 g per 1 hot dog).
It is a complete protein - it supplies all nine essential amino acids in adequate amounts, so it can carry a meal's protein on its own. The serving quoted here is measured by weight at 28 g, and it covers about 12% of the 50 g FDA Daily Value for protein.

21.8 g. The 1 oz serving used on this page weighs 28 g and so carries 6.1 g.
14.8 g. That figure divides its 21.8 g of protein per 100 g by its 147 kcal per 100 g, so it does not depend on serving size.
Yes. The protein in pastrami supplies all nine essential amino acids in adequate amounts, so it can carry a meal's protein on its own.
About 12%. One 1 oz serving has 6.1 g, and the FDA Daily Value for protein is 50 g.
